No, Geno is not The Ageless. Both are separate characters, with the later being a Snapshot (a perfect copy created by The Loop) of the other. The Ageless is his own person and has almost nothing to do with his original counterpart, having a personnality and goals very different from him. This title means that he is indeed immortal, or at least that he can't age. We realize this when we learn that he has led the Oathbound Empire for at least several centuries.
