Well no, not if accuracy is important.
SAI Global is the 'mothership' to a number of organizations. They offer a variety of services and perform a number of functions. I believe that their roots are in standards writing, a bit like ANSI is here. True, they have a registrar division (in NJ), but this shares nothing functionally with Excel Partnership.....
I was attempting to make a distinction about SAI, their role, other parts of the company and what has been known, by many, as Excel Partnership.
