Yes and No!
There are ways of overclocking a laptop.
Due to BIOS limitation you can use software that will overclock right after windows start.
Of course also due to the building nature of the laptop heating might be a problem.
Also there is no point in overclocking because thats not going to improve nb performance that much.
