Can I share a single Acrobat Pro license on two computers?

yes, and more.  you can't share your license with another person, but:

you can install the cc desktop app from here https://creative.adobe.com/products/creative-cloud on as many (mac and/or win) computers as you own and use it to install all (or some, if you want) of your cc subscription programs.

the only (insignificant for internet connected computers) limitation is that you can sign-in (and therefore start your adobe programs) on, at most, two computers without signing-out. because you can sign out from either (or both) signed-in computers using a 3rd computer, this could not (imo) be easier. https://helpx.adobe.com/download-install/using/install-apps-number-of-computers.html
