Based on real life and the movies, "Don" was right in the first place. James Bond and 007 is a codename, but a fictional one. It's a different person.
I read a book by some British spy defector (forgot his name, made some news when he defected) that a person occupying a certain position in the agency has the exact name as the predecessor. The author mentioned he was recruited by someone during college and he declined, he was recruited again a few years after by that same someone with the same name and ranking/position but by a very different looking person. That sort of thing is usually reserved for integral members/divisions of the agency.
It also showed in all Bond movies when M "changed" from a man to a woman (sex change?

) , and Q making subtle references (in the Brosnan movies) to the usual traits of James Bond/s or those who become 007.
As for the books, I have no idea. Haven't read it.
you also have to consider the fact that Bond is at least 7-10 years older than Bourne. Bourne is supposed to be in his late 20's, in almost every bond movie, connery or brosnan or whoever, he looks mid to late 30's at the youngest.
Because 007 is an elite position, based on the Bond mythos anyway. It takes someone with vast experience to be promoted to that position. A 40 year-old field agent would probably have more experience than a 30 year-old one, would it? Besides, if "00" agents reached that age it means that the agent is good for the simple fact that he's not dead yet.
James Bond also has the rank of Commander in the Royal Navy (you could see in the movies him being called as such.)
That means Bond could deploy a

to wipe Bourne's sorry ass.
Nobody mentioned it should be a 1-on-1 fight.
The question is, who would win in a fight?
I would still go with Bourne in a 1-on-1 fight even with all the available gadgets and weapons. Even with amnesia, Bourne could still kill a bunch of guys. Hunting down a sniper with a shotgun? I've never seen Bond do that.
