Typically it is not possible. There are too many varying parts between the years to allow it to fully work.
The 2009 and 2010 models have more similarities than the 2011 model.
Ultimately, i've not tried it between the 2010 and 2011 models, but with the difference in so many of the parts (the only real similarity in major components is the PSU).
SO you will only know for sure if you had them sitting side by side for comparison, then took the risk by fitting it to the machine. Sometimes there are minor component differences that handle voltage differently to other boards, so its definitely a risk, so i'd not suggest it unless there are many similarities between the ranges in question.
I hope this helps.
