Actually he is called the "son of the morning" not the "morning star".
The Morning Star is used only twice in the bible, both in Revelations and only once refering to it being a name. It is found in Rev22:16 and refers to Jesus.
Nice try! My Site is called the "Morning Star" and it wouldn't be if Satan had been refered as such.

And I will give him the morning star.
Re 22:16
I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.
