I doubt it, laptops are made specifically for one type of shell so no, don't do it.

The CPU is a PGA model and you can take it out from the socket and replace it with an i5 3337u. Make sure to uninstall the processors from device manager and click on update to indicate the correct CPU installed. Also update the BIOS to the latest version. You can also perform some tests to see where the performance stands.
