Yes, but it would only be possible via software overclocks, no BIOS, i wouldn't recommend doing this, cause laptops aready run hot as it is, adding more heat won't do it anygood, plus, you could probably only get 2.-ghz max out of it, and thats not really worth it imo...
you will be able to do it, but get a laptop fan mat so it has that extra cooling, because as mx344 said, they run hot anyway and overclocking will just add to this
