Sure you can. Anyone can mine from home, ROI is a whole different story though.
If you do decide to go ahead and mine, make sure it's inexpensive, energy efficient, and you view it strictly as a hobby, not a money printing machine.
I guess this is a key point. If you mine from home, you have to go into it expecting to lose money... It's a pity because validating the blockchain is an important function and it was awesome when the open book was maintained by the collaborative of all the people... Now it's maintained by a few big players starting to look like banks, hope they don't start charging fees like the banks
