They DO have the same socket.
BUT you need proper BIOS support and on many laptops, the chip is soldered to the motherboard making replacement impossible. Make sure your CPU is socketed!
Be sure to clean up all the old thermal compound, expecially if the old stuff was a wax. Radio Shack thermal compound works great, if applied properly it is every bit as good as the expensive ceramic compounds and is close to the performance of Arctic Silver (AS is only about 2-3 degrees cooler)! No I'm not kidding, it is that good!
With that said, I replaced the Celeron in my old HP laptop with a PIII and I am pleased with the results.
