Transplanting HD from early '08 iMac to late '11 MBP

[mlsusa]

My iMac is about to go out to pasture so I'm going to remove the new-ish SSD I had put into it and move it to my wife's laptop. I'm thinking of trying a straight-up swap -- i.e. no reformatting and rebuilding, just take out the old, pop in the new, fire up the machine. I figure worst case if the laptop rejects it or seems to run sub-optimally because it was built for a different model or architecture, I'll do a fresh build at that point, then maybe use Migration Assistant to copy back docs, pics, vids, etc.

Question I have is if anyone's aware of any harmful effects to the hardware from trying something like this?

Thanks in advance.

It will work if there is at least Mac OS X 10.6.8 installed on the SSD.

Thanks. Should've mentioned both machines are on Mountain Lion and are on auto-update so should be on the latest releases.
