It very much depends on the rabbit! I think some degree of stability and familiarity is good, but also think that some degree of novelty and change is good and keeps them interested in their environment. I wouldn't have thought that moving the food would be a problem at all, the water may be depending on how easy it is for him to find - try it and see, and keep watch until you're sure he's discovered where it is. I've moved water bowls without any problem before.
The thing you might have more of a problem with is moving a litter box - sometimes they might associate the box with the place to poop, but sometimes they might associate the location. So if you move it, he might move with it, or he might carry on going in the place he was before. I think just try it and see!
