No, as the Everstone prevents evolution. Although it isn't Grotles usual evolution level, if you remove the Everstone and level it up again to level 34, it will evolve. This will work with any level except 100; if you Everstone all the way up to 100, Grotle will never evolve.

In other words, with the Everstone it won't evolve, but if you remove it and level it up again it will.
