Yes, create three documents: Book A, Book B, and Common Pages. Then use File > Place to import the common pages into A and B (use show import options if you want to control how they’re placed, including bringing more than one page in at a time).

When you want to edit a page from Common Pages, just open and edit. Then you’ll have to click Update in the Links panel in A and B.
