To answer your question, no. As others have pointed out, that particular GPU is soldered into the mobo, and even if you felt frisky enough to try and replace it there's a good chance a different card wouldn't fit, wouldn't power up, or both, because that mobo and case wasn't designed to power, hold, or cool it.
In your case you're options are going to be buy a new laptop, and any sort of machine that would offer the ability to change out the GPU is going o be $2000+, or go ahead and build a desktop.
I faced a similar situation at the beginning of this year when I was considering either trying to upgrade my own gaming laptop, and people actually make kits for this (MSI GT70), or building a new gaming PC from the ground up. The upgraded laptop GPU by itself was $800 to $1000, depending on where you bought it from, and it would still give you performance 20-30% below the desktop equivalent and cost 3/4 as much as an entirely new desktop with respectable specs. In the end, I couldn't justify trying to heavily modify a laptop that even though was possible, it wasn't really designed for it, spend a ton of money and still come out with the specs of basically a mid-ranged gaming desktop, or I could stretch my budget a little further and build the beast of a machine I ended up with, and then add to it later and make it even more beastly (which is what I did)
