Persson started playing hockey in his youth with IK Viking, in his hometown Hagfors. He won TV-pucken with Värmland in 2000, scoring six goals and a total of eleven points in eight games. For the 2001–02 season Persson signed with Västra Frölunda HC to play for their junior organisation, and attend the hockey gymnasium in Gothenburg. Persson spent the majority of the season with the under 20 team in the J20 SuperElit. Playing 35 games, Persson scored six goals and ten assists for a total of 16 points. In the playoffs Persson played five games, scoring one goal and an assist as Frölunda won the Swedish under 20 Championship. Having played just three games with the under 18 team during the regular season, scoring one goal, Persson joined the team for the playoffs, leading Frölunda to a gold medal in the Swedish under 18 Championship by scoring four goals in a 10–1 win against Huddinge IK in the first game of the finals. He became the playoff leading scorer with six goals and three assists for nine points in three games. The following season Persson played 30 games in the J20 SuperElit, scoring ten goals and 19 assists, and five assists in six playoff games as Frölunda captured a consecutive gold medal in the Swedish under 20 Championships. Not having played with the under 18 team during the regular season, Persson appeared in two playoff games, assisting on two goals in the quarterfinals against Leksands IF, and scoring one goal and an assist in the decisive game two of the final against Modo Hockey, which Frölunda won 6–1, winning consecutive gold medals at the under 18 Swedish Championship as well. For the 2003–04 Persson was named captain of Frölunda's under 20 team. He played 36 games in the J20 SuperElit, scoring nine goals, 24 assists for 33 points. During the season Persson was called up to Frölunda's senior team, playing in two exhibition games and was on the roster for one game in Elitserien—Sweden's premier men's league—on December 28 in a 4–0 win against Timrå IK, though not receiving any time on the ice. In the J20 SuperElit playoffs Persson played five games, scoring one goal and five assists as Frölunda were eliminated in the semifinal against Modo Hockey. After the season, Persson was offered a contract by Frölunda to continue playing junior hockey and be used as a thirteenth forward with the senior team, but chose to sign a two-year contract with Hammarby IF in HockeyAllsvenskan—Sweden's second tier men's league. Persson only played 13 games with Hammarby's senior team before being loaned to AIK in Division 1—Sweden's third tier men's league—where he played five games, scoring three goals and two assists. After four successful seasons in Karlskoga, Persson signed a two-year contract with Luleå HF in Elitserien. Persson scored nine goals and eleven assists for 20 points in 51 games. On April 4, 2013, Linus Persson scored his fifth Elitserien playoff goal of his career, just twelve seconds into overtime of Game 4 against Färjestad BK, which broke the record for the fastest overtime goal ever scored in Elitserien playoff history. With eight goals and four assists in 15 games Persson was the scoring leader in the 2013 Swedish Championship playoffs. He led Luleå to the final where they lost the best-of-seven series in four games to Skellefteå AIK.
