Well, you'd likely damage the motherboard rather than the CPU. The sockets aren't the same. Even if you lived to be a thousand, you'd never get this to work, so there's no purpose to trying, even if you knew there would be no damage.
Or you don't actually have a 10th-generation motherboard (LGA 1200) or you don't actually have a 9th-generation CPU (LGA 1151). Conveying information that is both detailed and accurate is extremely important for asking technical questions!
