[The Terminator] What would have happened if Sarah Connor named her son "John Reese"?
gpt
There's fundamentally no change. Ignoring the entire paradox situation John is the destined destroyer of skynet. It will always know his name even if it's changed. In fact the only reason skynet even knew where to find John in the sequel was because of his foster paperwork that would have any name changes listed as well as his birth and adoption records. We even see in the Sarah Conner chronicles that using altered names and alias doesn't work as Skynet still finds records of him existing pre-judgment day. 

The only real changes would be Kyle Reese may suspect that there's more to his appointment as Sarah's protector than just a coincidence that they share a name. It still wouldn't dawn on him that he's John's father until he goes back to 1984 but he may clue in faster.
