Canned air rocks in a normal computer but Im not very sure about laptops. If you use it where the fan is, wich is very small you will distribute all the dirt and dust insidr the laptop.
Also it depends on the time you've used your laptop, if you smoke or have cats etc as variables to know how many shit you will find there. Ive opened several laptops and with time you tend to find a inch width plug of dust and shit where thr fan is. Just imagine distributing that, wich prolly you wont be able with eficience, with an air canned machine.
You better open it with care, remember where every screw goes (normally there is like one million in diferent sizes) and take advantadge of opening the laptop to place a bit of cooling paste in the processor.
