A seemingly obvious question is whether dark matter could provide an equivalent result. I'm not really sure, but the paper's authors seem to be saying 'no' in this passage: Equations (B2), (B5), and (B7) are the main results of this section. They provide an expression for the phantom mass that sources anomalous effects in the inner solar system. As discussed above, these effects are absent in Newtonian gravity and hence absent in any dark matter model. Perhaps someone more knowledgeable could comment on this?
