The actor confirmed that his alter ego Jim McDonald will be back on screens within the next few months and be part of the show's 50th anniversary episodes.
Lawson told PA that he is currently unaware of Jim's comeback storyline, but suspects there is a possibility that the character could be killed off.
Asked whether he could reveal any plot details, he replied: "I'm going back into the Street for a few episodes... I haven't seen the scripts and even if I could, you know I couldn't. But I have no idea. I suspect either I'm going to get killed, or..."
Show producers have revealed that a number of characters will lose their lives in December when a tram dramatically crashes on to the cobbles.
On whether Jim could be a victim, Lawson said: "I don't know. I suspect I've probably been in the frame for it - whether or not I'm going to be, I've no idea, to be honest with you, and if not I don't know what I'm going to do. But I'll be around for the 50th anniversary."
Lawson is also involved in Coronation Street's forthcoming anniversary play at The Lowry theatre in Salford, having signed up to narrate the comedy production.
