It's very possible. Wonderbot also makes a cryptic remark in Episode 2: "As I thought, Matsukaze Tenma is..."

Another theory is that future!Tenma is Supporter X. Like, maybe Time Travel isn't as far away to develop as they seem to think in the anime.. After all, both future teams we've seen so far have time-travelled, and even Zanark's motorcycle can do it. And Dr. Arno is an expert in the field - becoming an expert usually takes more than five years, and way more than ten if you're reowned. (Like Dr Arno seems to be).

Zanark introducing himself without a name... it seems likely that 'Zanark Abalonic' is just something he made up on the spot. And according to Gamma, 'Beta' is just an administrator code. So for now, it doesn't seem like Alpha / Beta / Gamma are the captains' real names either...

It actually seems very plausible to say that no-one in the future has a real 'name'. Rather, they just make it up themselves, or are allocated a name to use for themselves.
