I agree it makes sense, but it doesn't really fit genre. Most telekinetics tend to be psionics or mages, who are generally a lot squishier and less competent at close range. Putting a grab on them could be considered similar to the Damsel Incapacitation Attack
*, which actually makes sense for PCs who need to gesture to make their powers work. Making MO Escape an optional House Rule could work though, especially since that could also allow a Power Loss Complication vs Grabs if you wanted to use that genre convention in your game.
EDIT - on the other hand, your avatar is a GL and using Lantern power to escape Lantern grabs makes perfect sense.
