switching hd in macbook

[remorseless]

I have a first gen macbook with an intel core duo processor. My sister has a second gen macbook with an intel core 2 duo processor.
I would like to upgrade to os x lion, and my sister would not.
os x lion does not support core duo.
os x lion does support core 2 duo
Is it possible to switch the two hard drives and RAM in the computers so that I would have the core 2 duo, and be able to upgrade to lion?
Thanks for any help!!
