Yes I think its soldered too , is there a way to desolder it?

Picture is a little small and blurry for me to tell actually. My guess would be no. I see a layer of protective plastic that is covering up around that area. If it looks like a discrete card that can be removed then it should be pretty clear to see.
If there is no separation between the motherboard and what the GPU is attached to, then it is likely a BGA chip soldered to the board.
No, not really a serviceable part. With the proper equipment you could locally heat that up and remove it, but you would need exact spec sheets for the proper temperatures and how long they should be supplied. Generally the precision required is only available at the factory that built it. And for the price of purchasing the proper equipment you could go out and a buy a few laptops.
Even then, no guarantee that the other board would accept the chip.
