The hardware identities of the iPad is hashed and sent up to apple, including IMEI and serial match. If it does not fit, the server will refuse activation, so once you replace the Cellular Board, you can no longer activate activate this device unless you swap it back. Your only way is to hackitivate it, or factory refurbish the device to reassign and re-register hardware identities. Which is impossible for any of us to do.
