I'm sure they would if you asked them to. Anytime they replaced the harddrive in my laptops under AppleCare, it came with a fresh install.
I asked that question and the agent said: No, the recall doesn't require us to install an OS. In fact, the agent specifically said that Applecare doesn't require this either. I checked the Applecare agreement and it says nothing about this situation.
Of course you're right that they *might* install an OS nonetheless. On the other hand, I'm still running 10.6.8 (I'm too cheap to give Intuit money for their Quicken-for-Lion "upgrade") so I don't want the latest OS. Would Apple even want to get involved with installing an old OS?
Now that Apple has pushed back this recall, I imagine a number of people will bring in iMacs with old versions of the OS. I doubt Apple wants to give them all free OS upgrades. I think I'll first experiment with my daughter's iMac (also recalled) which I did upgrade to Lion (but not ML).
