Can a pardon be revoked? That would be funny.
Serious answer: no.
Once a pardon has been delivered and acted upon, it is irrevocable based on the principle of double jeopardy. The only time a pardon can be revoked is when it has not yet been finalized and acted upon. This has only happened twice in US history, once when George W. Bush revoked a pardon on Isaac Robert Toussie (largely because it came to light that Toussie's father was a Republican political donor - this was back in the era where politicians still pretended to care about conflicts of interest) that he'd issued a day earlier but which had not yet been finalized; the other was when Andrew Johnson attempted to pardon two fraudsters in the waning hours of his presidency, but when his successor, Ulysses S. Grant, took office he immediately issued an order for the pardons to be rescinded, managing to get the message to the prison where the two prisoners were being held and order the warden not to release them while the pardon was en route. The two con artists appealed, claiming that the presidency could not rescind pardons and the case made its way to the Supreme Court, where it was ultimately ruled that because the pardon had not yet been acted upon, they were not considered "final" and it was within the authority of the president to decline to go ahead with the pardon.
