There is a chance - yes, but there's a lot of other evidence that he was involved in its creation (not just the 10+ years he talked about bit-gold prior to bitcoin). Bit-gold = bitcoin. My guess is that someone (like Hal Finny) implemented it with him but he was the originator of the idea and wrote the paper on it. Finny most likely had the original keys or he intentionally got rid of them on purpose (which explains why the wallet hasn't been active). Those are my guesses but the language in the paper very much gives me the impression that it was written by Nick Szabo.
