No, because that CD was not written by Takahashi. she merely only gave them permission to put the story in wideban format and gave them manuscripts of the final chapter that comes along with the CD: http://rin-sess.com/inuyasha-drama-cd  And that she had zero control over what actually went in the CD. Therefore...the CD is not canon.
