[W40K] Is the God Emperor the same type of god as the chaos gods, or is he a different one?

Very different. The Emperor is more akin to the Eldar gods, a deliberately created warp-presence constructed out of the fused souls of Earths Shamen. Where he differs from the Eldar, though, is that the Emperor was then bound in the body of a mortal (though he was made ageless by his immense psychic might) whereas the Eldar Gods (originally created as psychic weapons) remained totally in the Warp. 

The Chaos Gods, however, were created by the gradual accumulation of strong emotions rather than any specific creation-event, and without any specific goals in the creation. There are some sects of Chaos, such as the Magi, however, who think that they can create a 'Chaos Emperor' by manifesting one of the 4 Gods in a mortal body.
