I just went to Seattle for the interview yesterday. Asked this question of the Canadian interviewer. ("Can we enroll Iris scan prior to actually receiving and activating the NEXUS card"). He informed me that YES we could go to any Iris scanning location, show them ID (Passport, DL, etc.) and the number on the Interview Letter we got and they'd link them up.
I didn't wind up going to Vancouver to do both interview and Iris (as I had initially planned) due to a Seattle appointment opening up earlier as well as basing on the advice above, but it sounds like I could have.
FYI.
