A demon can die, but only if you attack the actual demon. A demons body in the physical world is just a projection or manifestation. Even if you kill that, the demon will just be banished back to the warp at best. Warp powers can hurt a demo in the warp however. So a psyker or powerful weapons could theoretically kill a demon. Though knowing of this weakness, demons will take efforts to avoid being killed in such way.
