If the connector on the back is the same (after you remove the iMac-specific interface board), then you shouldn't have any problems. However its been a few years since I've opened a slot load iMac, so I'm not sure about what they use.
However, your tray load iMac should have no issues handling a standard laptop DVD drive, even a working pull from most PC laptops. I've used a TEAC DW-224E (Combo) borrowed from a Toshiba Tecra S1 in my Rev. D tray loader before, and it worked perfectly.
