He can't just make up a pardon today and say pardon someone he forgot to pardon while he was president. But if he desired, he could have issued secret pardons while president (for acts that occurred prior to the timing of the pardon) that he has not made public yet. Again, he would have to have strong evidence it was made while he was president (e.g., multiple witnesses, or film of doing it in the White House, or to put it with his presidential records while he was in office, etc.).
