If you mean the current set of heroes who use the name 'Green Lantern' the answer is "Nope, not really." Ever since Hal Jordan first took the name, Green Lantern never had a teenaged superhero sidekick. Typically, the role they can be play in stories (exposition-requiring trainee, hostage, machina for the deus, etc) can be filled by another member of the Green Lantern corps, often a trainee.
Once the Green Lantern Corps expanded to include 2 for each space sector, this became even easier to write in, as it was no longer rare for two Green Lanterns to meet while 'on the job'.
