Right, the locations in a memory palace are just a form of "peg system" [1]. The advantage it has compared with a "link system" [2] is that forgetting one link doesn't mean you lose the rest of the chain. You can also jump to an arbitrary point in your palace. You're right in saying the use of a physical location is just a convenient but not fundamental part of such a system. A system that really pushes the idea that the pegs you attach things to can be arbitrary is SemCubed [3], a system where you create a large 2-dimensional grid of "pegs". It also makes use of the Mnemonic Major System that I'm a big fan of.
