You can delete the game, redownload the trial client, and login and it will let you play without the disk.

I've tried this once or twice I think. It never seems to work for me.

This. The key thing is you need at least one of the expansions as a digital purchase. I have physical ARR, digital HW, physical SB (don't ask me why, wallet was drunk). Deleted the game, downloaded the 'trial' from PSN, waited a day for download because Aus internet, logged in and have been without a disc since.

I haven't digitally purchased any part of it, just the physical disc, unless the free trial counts (programming-wise) as a $0.00 purchase.
