They definitely aren't the same person. Their facial features are completely different, and we know they have been in completely different locations during the same events. (IE: Tatara taking part in the attack on Kokuria while Arima was elsewhere, Tatara attacking Amon and Takizawa while Arima was finishing off Kaneki) We also have Eto complain about how brutal Arima is, since he was the only person that actually managed to do her serious harm. And if Arima and Tatara were the same person, Tatara wouldn't need to ask about Houji -- he would already know the answers about which Ghouls CCG has in their custody.
