Nope, you need to have IP route for it. If you choose not to tell the second
router that it can do it, it would never even try.

Repeat after me "My router does not  call ms. Cleo to find out what I want.
Router follows my instructions to the letter. I forgot to tell my router to
do something. It therefore refused to do that something. I shall tell my
router to do what I want it to do. It will follow my direct instruction."

Now either configure a secondary IP on the second router, or create IP
route pointing to the router that knows how to get to the destination.
