No, it can't. It can only reproduce a subset of galaxy rotation curve observations. It cannot reproduce other observations at all (such as the amount of structure in the universe as compared with the amount of baryonic matter that is consistent with Big Bang nucleosynthesis, which is about the same as the amount of matter we can see, but is much too small to account for the amount of structure--gravitational clumping into galaxies and galaxy clusters--that we see).

- pdonis 4y ago> it's not nearly as rosy for DM or dire for MOND as you imply According to that one paper, perhaps. There are lots of papers published in this area of research. If you want to say the jury is still out on a final resolution, yes, I'll agree with that.
