[Back to the Future] How could George McFly publish that book?

George McFly published a book about meeting the love of his life, Lorraine, because of an alien; Darth Vader from the planet Vulcan.

This all happened back in 1955 before Darth Vader or Vulcan were things, but in 1985 they are both very well established in science fiction.

Did he change the name to deal with copyright, or try and keep it true to his life's experiences? Could he even publish the book if he kept the real name of the alien in it?

Do we know that the 1985 book used the names Darth Vader and Vulcan?  The chance of George even remembering the names were remote: he heard them once, 30 years earlier, having just woken up and possibly being in a state of shock.
