You are correct in your assumption that legumes can be nodulated by
rhizobia and be mycorrhizal as well.  I know for sure it occurs in
Pisum, Trifolium and Medacago having read papers on all these with
nodules and VAM.  I don't know for sure if Alnus or Myrica and the
other streptomycete symbionts but I would be surprised if it is not
the case
