I would do that (on the book pages) using a nested character style for style the chapter number and a frame break or forced line break to separate the title (since I assume you have/want them on separate lines).
I wouldn't do that if you can avoid it, especially the frame break, since those will wind up in your TOC as well. Better to just make the frame just fit the part of the text you want in it.
