If you never intend to build on top I guess you could - though outlawed in most areas to break down the block and push into the hole, because that makes it a landfill. In some areas illegal to bury the foundation too, though not in many I have seen.


Obviously, if a place a house might be built in the future, having open block and voids between the blocks (which the dirt will move into, causing a lot of settlement) is a bad idea - as is having existing wall left in place and end up under a slab-on-grade house.


If you want to leave it, move common thing is to perforate any basement slab with a number of holes (usually just jackhammered) and gravel them over as a filter to prevent pooling of water in the basement (making the fill area a swamp or, after settlement, a pond), knock off the top row or few of blocks with the dozer or backhoe and dsipose of them (or use to build a retaining wall or such, if they were not fully grouted and rebarred) to get the wall below grade a foot or so, then backfill with desired type of fill (typically common fill).


I have also seen the foundation left in place, partly filled all around to bury the wall, and turned into a pond that way (in areas with enough rainfall to do that, or with surface runoff directable to it).


If you leave the foundation in place I would get some measurements from property corners, trees, etc so it can be relocated in the future in case of development plans.

BTW - don't forget to check on utility (including any septic sytem connections) terminations - preferably cutting/capping all lines at their source or connection to existing house system (if that is the case) and cutting all electric/communications lines at their source, but at least ensuring they are located and terminated (for pipes) well outside the foundation limits.
