Is increasing ROM a way to progressive overload?

I do Push-ups at home. I find it much harder and I could do less reps when I do them putting my hands on two stacks of books. I originally only did so to make it easier on my wrists but find it actually harder with the extra ROM.

I guess it has to be that you have to the same weight but more distance. Then is it a good way fo progressive overload? Like, I do weighted Push ups of on the floor, then do the same weight with two push ups handles to make it harder. Then repeat with heavier weight?
