Yes, you can.
Duplicating a page is useful when you want to create a similar page but change some of the content (e.g., ABM pages) or testing different versions of the same offer.
In the Pages list view, hover over the page you want to duplicate and click the duplicate icon that appears.

A copy of the page will be created for you instantly.

When you duplicate a page, everything comes with it: page content and images, layout and styles, version and drafts of the original page, etc.
