Is it possible to upgrade the video card of my Asus k42j laptop?

Depends on the laptop, but for the vast majority of them, you can't.

The same goes for the one you have there.
 
I searched for you laptop model, and it looks like the chip is soldered to the motherboard. So no.

Superman, it is possible for a few laptops. I've done it in an old Dell Inspiron I have because the original card only supported DX7.
