Moz is advising that a page has too many of the same keywords.

But this sub-category page includes products that have the keyword in the product name. Should I be concerned?

Depending upon the keyword and context this could be an issue.   The biggest concern is obviously the appearance of keyword stuffing the page, and the percentage of content on the page that is not that keyword.

Is the keyword necessary in the product name?   E.g. A category of Rome Tours, and you list all of the tours as  "Rome Tour of Pantheon", "Rome Tour of St. Peter's Square", "Rome Tour of Spanish Steps", etc...

I could probably be more helpful if you could provide an example...
