There were no database changes between 3 and 4 so it should be safe, but I strongly recommend against running multiple versions of calibre on the same library, because there is no actual guarantee of backwards compatibility. For instance the upcoming calibre 5 will use sqlite FTS which means you wont be able to delete books from the library with versions of calibre not compiled with fts support.
