Muslims believe that it is the same god but that Christians have misinterpreted the words of Jesus.
And misreported them, yes. But if you add that belief to Christianity you don’t get a syncretic combination of Christianity and Islam, you just get Islam, in much the same way as the people who call themselves “messianic Jews” are generally regarded as Christians who find it convenient for strategic reasons to call themselves something else. The Wikipedia page for “Messianic Judaism” does call it a syncretic variety of Protestant Christianity, which is kinda reasonable, but empirically it doesn’t seem as if this actually leads to less tension between actual Jews and “messianic Jews” than between actual Jews and Christians who call themselves Christians. I suspect something similar would be the case for any Muslims who tried calling themselves “submitting Christians” or whatever.
However, I concede that Baha’ism is a pretty successful syncretic combination of (among other things) Christianity and Islam. I expect other syncretic combinations of “Abrahamic” religions are possible too.
Syncretism between an “exclusive” religion and an “inclusive” one is definitely possible. I think there’s been rather a lot of it in India. But I think in these cases followers of the “exclusive” religion would generally consider that the result is a caricature of the true faith, and would not feel any more positive about it than about followers of “inclusive” religion who don’t mix any of their religion in.
