As far as I'm aware, any AF plane carrying POTUS can have the callsign AF1.
It's not restricted to any one plane.
One interesting point to note was that when uncle Joe flew to Delaware, that plane did not squawk as AF1.
Do you also not find it interesting that after many people pointed out the fact that he had not yet flown AF1, that they make a drama and a point of this?
For that short trip he could easily have flown in Marine 1, it would have been quicker than flying to Andrews first.
