No, the A is not the same as B sharp. B sharp would be the C note since there are no music notes between B and C. The C note would only be called a "B sharp" if C sharp is used in a key, since proper music note naming only allows for one note of each base name ("accidental" notes excluded). So rather than have two types of C notes, you would have a type of B note and a type of C note.
