Yes, but it is unlikely. More likely would be: "I read the book halfway through."

It does generally imply that the action was completed, but it could be used otherwise in ceratin circustances. For example, if a parent was accusing their child of neglectin their studies and they said this, it wouldn't necessarily mean all of the book, but you'd need a clear context for this to be understood. ;-)
