Yes...but no.
When we're talking about the base OS (terminal/textmode stuff): yes, the base is the same.

Ubuntu-MATE makes use of the MATE desktop which is fast, snappy, humble with CPU, GPU, RAM and battery and therefore overall a better OS for battery operated equipment (Laptops and tablets) or equipment with non-adequate cooling (for instance HP-laptops).
You really would have more chance on a solution here:
Ofcourse we would like to help you but since a very big and important part of your system is very different from ours, we might not have the best situation to come up with an adequate solution.
