Without knowing what exactly is causing the crash, it is entirely possible, perhaps even probable, that leveling up and reducing the duration of the fight is more than enough to avoid the game crashing issue. Sure, it's possible the bug is just a matter of the boss reaching a certain health level, but there could easily be a variety of other factors involved.
Another option is to repeatedly quick save throughout the fight, and when it crashes, reload to just before the crash and see if you can beat him down farther, or it continues to crash. I'd recommend maintaining a clean save prior to any fight though, on the off chance that quicksaving during the fight corrupts the save file.
If you end up with a save game that will crash upon one more hit on the boss, that's a game file I'm sure Bethesda would be interested in receiving to look for root cause.
