Strongly not recommended especially on laptops. The mechanism by which the keycaps connect to the keyboard is very delicate and subject to injury by removal. Sure, you can muscle them off, but can you reinsert the metal pin into the plastic hinge of the keycap without pranging it?
I speak from first hand experience, both in mangling laptop keycaps and delivering the last rites to keyboards murdered by other well meaning amateurs.
It can be done, but it is a very delicate operation. And if the obstruction is a mechanical one, that is, something physical impeding the physical motion of the key, then it can likely be removed, dissolved, dislodged by other means (canned air, a little bit of solvent like water or alcohol, and much shaking and blowing and shaking and vigorous keypresses, rinse repeat). If there is some other problem, like a liquid having been spilled on the keyboard and then penetrated beneath the silicone membrane switch, impairing the electrical contacts, then removing the keycap is not going to help, and you still have the problem of getting the keycap to stay on when you try to replace it.
One idea if you're set on removing the keycap, google up a diagram of your exact keyboard and try to get an illustration of your keycap hinge mechanism. Then you can know what you're up against before you begin your demolition work. Or you can just work on exercising your right pinkie.
