Can it be done: Yes. Can you do it successfully: No.
LOL, no. Not possible to someone without serious knowledge of computers.
Maybe. The physical dimensions are different, So you will have to wedge that motherboard inside the desktop case. Might cause a short circuit.
Also, the desktop's hard drive Windows license will not be valid to use with that laptop's motherboard. You will have to use the laptop hard disk's operating system.
So now you have converted the laptop to a desktop that needs a power cord and cannot be portable anymore. Happy?
