Well yes, that does effectively end things but I wouldn't call that a "Good Ending" because it's not really earned. This method is possible and not too far to what was going to happen, but it won't achieve the best possible ending. In that sense, this "Bad Ending" fits the definition you had earlier.

If the Big Bad is defeated and the world does not come out of the story worse off than when it went in, it's a Good Ending, by most modern conventional definitions, regardless of whether said victory was 'earned' or not.  -_-
