You can't soul trap a dragon in Skyrim because they're obviously too powerful to have their soul be contained in a soul gem, however shouldn't Azura's Star be powerful enough to hold the soul of a dragon? If you've played Morrowind then you'll know the Star can be used to soul trap Vivec and Almalexia who are both basically gods and I'm sure that Vivec at least is more powerful than a dragon considering CHIM.
