Yes, you can but you must realize that the potential audience for poetry is much smaller than the audience for informational-type hubs. I have two HubPages profiles. One for my creative writing, mainly poetry and another that I have monetized and write informational, educational and review-type hubs. The difference in traffic is enormous with latter getting the most.
HubPages has an active poetry/creative writing community but I don't know if it is big enough to generate enough traffic to produce substantial income. Here's to hoping I am wrong.
