Coris is a genus. H. tripsilus and H. chrysus both fall under genus Halichoeres, so therefore no, neither are coris wrasses; "yellow coris wrasse" is a misnomer.
the liveaquaria page you linked to has misidentified that wrasse. the picture shown is of Halichoeres leucoxanthus, another small Halichoeres wrasse. either way, H. trispilus and leucoxanthus both reach a maximum of 9cm. At a max size of 40cm, Coris gaimard will be a much greater threat to your inverts.
