My best guess is it's okay to drive, just irritating. What you're pointing to isn't going to cause a noise but slop in the upper mount can let the shaft of the strut wobble and knock around. One problem with those upper mounts, particularly on the front, is you can't tell they're worn until the strut is disassembled for replacement. Then we have to find the customer and tell them they need more parts than first expected.
For a horrible rattle, I'd be looking at anti-sway bar links, rubber control arm bushings, loose exhaust pipe hangars, ... Things like that. Struts and upper mounts don't make that much noise when they're worn. If you can post multiple pictures of the rear suspension on one side of the car, I can copy it and add arrows to show which parts to inspect.
