You’re asking if head trauma can cause brain damage in animals?
Dogs do have thicker skulls than humans, wrapped in more muscle than humans. Both of these make the skull better at absorbing shocks, so much less force should transfer through to the brain.
As long as your dog isn’t regularly running headfirst straight into the corners of tables, I wouldn’t worry too much.

Wellllll, kinda.
There’s a no, in that retarded has the strictest meaning of being an inborn developmental barrier rather than an acquired one, but it has had so many usages over time that I don’t think that more limited usage matters.
So, it’s a qualified yes.
Animals other than humans can definitely suffer chronic tbi (traumatic brain injury) effects, with symptoms ranging from mild to severe enough it would cruel to not euthanize.
Dogs in particular can develop problems that would match colloquial usage of retarded for sure. I’ve personally seen dogs that took bad hits from cars have worse effects, but having memory losses, apparent cognitive loss, and definitely coordination loss are pretty common with even milder head trauma in dogs and other animals.
However, that’s not to say it always has to be from major trauma. You can have issues with repeated minor injury, in humans and animals.
It’s unlikely the level of play you’ve described would be a problem though. Just running into things on zoomies isn’t likely to cause the kind of bouncing around of the brain it takes to cause neurological deficit. It could, though I suspect it would take longer than most dogs live
