That’s a good question, my first thought is I don’t think so. I think the senate can challenge a president’s pardon.

The Senate, nor any other body, has approval over the Presidential pardon authority. The Congress (either house) can conduct an inquiry into events and pass resolutions voicing the sense of the House or Senate, but the Presidential Pardon authority resides only with the President.
