No, it's called "dark matter" because it appears not to interact with electromagnetic radiation but has mass. We can observe it indirectly through its gravitational influence, such as altered galactic rotation curves and weak lensing. (If we hadn't somehow observed it, and we didn't have a theory that predicted it, why would we think it exists at all?) Regardless, the point I was getting at is that confirming or denying the existence of the Higgs boson would have little or no direct impact on our understanding of dark matter. (I'm not a physicist, but this is my layman's understanding of the situation, and I haven't heard any physicists claiming otherwise.)
