I haven’t read any commentary to this effect – probably because I haven’t read the right stuff, possibly because authors still have to take into account people’s desire to compare Jesus and Muhammad, religious figures. It’s uncommon in my sources, but not unheard of – and again, this may be a problem with my sources – to find a recognition of the equivalence of Jesus and the Qur’an, which seem superficially dissimilar, but which would both be designated in their respective traditions as Word of God. For that matter, Jesus is sometimes designated as the Word of God in Islam, too.
If Christian-Muslim dialog is going to move past the possible obstacle raised by the doctrine of the Trinity (is it “assigning partners to God” or not? does it fall afoul of the Quran?) in the context of the Quran, or alternatively, raised by the Quran with respect to the doctrine of the Trinity, it seems to me that it will occur somewhere in the neighborhood of this realization, that both religions have traditionally treated the Word of God in fundamentally the same way.
