Any way to fix this type of dent?

Solution
There will be no warranty resolution on this unless they just WANT to be super cool about it. Refurbs are always purchased with a disclaimer based on a letter grade as to what manner of damage you should expect to see. If the machine works properly they won't do anything.

Say thanks and enjoy your mildly damaged laptop as the gift it was.

Solution
The only way to fix it is to remove the top and bend it back to its original position. It must be removed because the metal will flex before it deforms and you must bend it beyond what is possible while it is still in place.
