Third-party product makers don't call out an individual model like 'iMac" in requirements. They go by processor type and OS version.
Go to this page: http://www.wacom.com/en-us/products/pen-tablets
Click on any of the seven models images. Once each model's page loads, click "Specifications" at the top of the page. Expand the resulting table to see system requirements. Some models show requiring macOS 10.8 and others macOS 10.10. If you have the 2017 model iMac, you already exceed that by a lot so should be OK with anything they sell.
