No, probably not, because even the oldest FF version it runs on is FF48. And it's not a xul-addon, but a Webextension addon, those are not compatible with K-Meleon and current Palemoon.
Chances are much better for this one, a Palemoon fork of the last clean Stylish:
STYLEM
https://addons.palemoon.org/addon/stylem/
Just try. Perhaps runs easily, or perhaps needs a bit fiddling in install.rdf, don't know.
But it's also possible to continue using the old clean Stylish 207 version, if accidental updates are avoided. A backup of it:

(PS: Mozilla has announced to DELETE ALL xul-addons very soon, that is the type which older Firefox/modern K-Meleon+Palemoon need. Mozilla's support for the last Firefox-version which still runs that xul-type ends around Sep.5, so everyone better grab quickly all sorts of addons they may need for KM in the future!)
