There is a lot of overlap between those two subjects, but they are not the same.
Because covid has had a big impact on the CFL, as well as "Other Leagues and Entertainment", I think a rule banning talk about covid would be absurd. Equally as absurd would be "you can talk about covid disrupting this upcoming season in the CFL, or its impact on the NHL season over the past 14 months, but not mention a large part of the puzzle (various governments/leaders making/removing rules)"
The original spirit of the "No politics/religion" rule was to steer topics to a more civil debate, because those topics tend to get a lot of people really fired up. A moderator will usually step in when a discussion gets too far out of hand and either lock the topic or tell the people involved to take it to private messages. I don't think nitpicking about what counts as politics would benefit anyone.
