Can I use a laptop CPU in a desktop

Hi, this is my second question for today. While I was reading reviews days ago, I was actually planning to get an AMD processor but then I saw how good Intel chips were, so I decided to go with Intel. However, when I looked at the price difference, I really had to think things through, but I came up with a probably stupid idea during the process. I have an HP pavilion dv5 - 1235dx laptop right now which has an Intel Core 2 Duo T6400 processor and I wondered if I could possibly get the processor and plug it onto a new mobo. The only reason why I wanted to get a new rig was because I could not upgrade the graphics card of this laptop, which gave me limited options for games. I have not tried to open my laptop yet to check the components, but maybe there's someone among you who have tried this before. I do hope someone can tell me if it's possible or not. Thanks a lot!
