No, he couldn't have, all the covenant ships in the region ended up at the Unyeilding Heirophant, all the ship there were destroyed or really badly damaged.
And I doubt the monitor could have taken a ship, note that sentinels REALLY dont like plasma. And if he had stowed away with the chief, he wouldn't have had a way to contact the covies without them finding out. It doesn't add up.
