Hi, Lisa. What a timely question. I am today/tomorrow wrapping up a Data Doctors video on just this subject. Linda listed a good link, and the video will say the same thing. If the data has no relation to the profiled person, not only should it be deleted, but headings/sections like User ID, Record ID Number, Data Changed, etc. will generate Suggestion 853.
So, yep, you're on solid ground here.
