Of course. Generally, most god names or important characters (or summons on certain games) are taken from certain beliefs.
For example, Quezacoatl (I think I have the name right) is used in Final Fantasy 8, as a god of thunder. Coincidentally, Quezacoatl is also an Aztec god, and I think it is thunder as well. I've also heard of Shiva being a god of another religion, though I won't say what I think it is, until I'm sure.
I think they do that to add a splash of familiarity, but also adding an aspect of creativity.
