Can this laptop be upgraded?

[Celestial Towel]

So I recently got a Dell Inspiron 15 i5548-2500SLV, and I'm not sure if it can be upgraded. I feel like getting a Samsung Evo 850 or a HyperX FURY SSD. Would the laptop be compatible? I don't want to take the back cover off as it's one whole piece of plastic.

Help is appreciated!

Changing the drive? Sure.
It should be under it's own little panel on the bottom
