Forgive my ignorance but is it not possible that there just wasn't a difference between Neanderthal mitochondrial DNA and H. Sapiens mitochondrial DNA? If it is passed along unchanged except for mutations is it possible there simply hadn't been any changes since our last common ancestor?

We have sequences of Neanderthal mitochondrial genomes, and they're significantly different enough that they can be used in reconstructing a phylogeny.
