Changing Sandy bridge to Ivy Bridge Mobile CPU? (Y570)

After several attempts at trying to communicate with the 'Tech Support' center for Lenovo, I decided to try a different option.

Does anyone over here know if it is possible to replace my i5-2410m (Sandy Bridge) processor with a i7-3615QM (Ivy Bridge) processor?

I know I can change it out for an i5-2670QM, (Sandy Bridge). But there seems to be zero documentation as to replacement with an Ivy Bridge chip.
