Someone on the forum contacted the CIC call centre about this. They were told, yes you can, but it will not be in the draw if you already have an outstanding application. I have no idea how accurate this is. See http://www.canadavisa.com/canada-immigration-discussion-board/can-a-cec-old-rules-applicant-apply-under-cec-express-entry-t263834.0.html;msg3909215#msg3909215
