Well, the best thing to do is to contact Acer Suport and check with them. They must have information on this, because you may encounter bios problem like bios error code due to cpu not compatible with board etc.

Make sure to check with Acer, which SL number for the CPU that have been validated with the board.
One more thing, i guess that you already know this link for the CPU:
All the best,
