A Dragon would not change his/her/its name for any reason, this is because the name carries great power to the Dragon but also great pride.

Do you think that if a Dragon could change names that Paarthurnax (Ambition-Overlord-Cruelty) would change his to reflect how he has strived to overcome his nature.

And as you all brought up Numinex when he forgot his name he died. If that doesn't show the great importance of names to Dragons then nothing will.

A Dragons name reflects who they are at birth hence how Paarthurnax's name shows how he was supposed to act under Alduins rule.

So no they are not the same Dragon. Also Blade Master, I find it very unlikely that an Imperial Battle Mage had a pet Dragon the Starlover's Log is something written out of love and not lore.
