It can of course. The same way I can just produce random noise and say it is music (avant-garde), and those who don't like just understand nothing in art.
Or more illustrative analogy: if it was generating text instead of music, and produced a sequence of words - some unfinished sentences, or maybe even complete sentences, maybe even sharing subjects (names) sometimes between sentences. But the whole text does not deliver any story. But you say: "maybe it's a story, where all these words follow each other". Well, maybe, for someone. Maybe it is anvant-garde poetry.
Finnegan's Wake is packed-full of self-referential meta-data and has a highly coherent structure.
In this sense, it's relevant to the discussion because it may appear to have been created by Markov chains whereas in fact it's intelligently molded and makes (more and more interesting) sense from the many perspectives you start to have as you spend your life with it.
Because for it to be that you'd need a workably good - if not fully complete - definition of classical-music-space. And this clearly doesn't have that.
