No. There are major errors in your and GP's reading comprehension. The article is absolutely clear it is talking about Edinburgh's school of informatics.

Immediately after spelling out the university's full name in the preceding sentence, the article says "The top-flight Russell Group university’s school of informatics claims there are 'problematic issues related to computing terminology'"

That is the only mention of the Russell Group.

Reasonable people may disagree, I suppose, as to whether the University of Edinburgh deserves an epithet like "the top-flight Russell Group university," but no reasonable person can disagree that that is exactly what the authors did.
