In the United States, he was a regular in the soap opera The Secret Storm on the CBS network from 1960 to 1964, playing Peter Ames. In 1974 he replaced William Prince as the character of Ben Travis in another CBS (later ABC) soap opera, The Edge of Night, and in the 1980s appeared in several of the Perry Mason revival TV movies, as District Attorney Jack Welles. During his career he also had guest roles in episodes of a variety of other popular British, American and Canadian television programmes, including: Doomwatch, The Littlest Hobo, Alfred Hitchcock Presents, Ironside, The Saint and The New Avengers.

During his time in Canada, Linder worked as an announcer at CKGB Radio in Timmins, Ontario.

Linder's last work was as Syd Grady in two episodes of the television series Sweating Bullets in 1991. He died the following year at home in Canada of complications from emphysema.
