Works is a completely separate program. Word and Works share nothing. It is safe to remove. As for reasons to keep Works… in my option? None. Word has so many features, however most of them are “advanced” and not present in Works. The biggest reason to use Word over Works: Auto-Correct and Spell Check. Both are superior in quality in Word, compared to Works. Basically, Works is the free version of Word for people that need a word processing program but don’t want to spend 200$ on Word. So, if you have Word, you don’t need Works.
