7S and 8S spacing is just a tiny bit different. 7S Shimano is 5mm and 8S Shimano is 4.8mm. So you can sometimes go back and forth with the 7/8 shifters/cassettes, but it does not always play well. It can be tricky to get it setup just right if you mismatch.

I used many 8sp minus 1 with 7sp shifters and all worked OK.
