It wouldn’t be a funeral Mass because that term only applies if the remains are actually present in the church at the time.
As for a “memorial Mass” that depends upon just what you mean by the word. It’s not wrong to use the term “memorial Mass” (in fact, it’s a rather common and often perfectly appropriate term) but at the same time, this is an often-misused term. Allow me, please…
A Mass is never celebrated “in memory of (someone)” (at least not literally) but the Mass is celebrated “for the repose of the soul of (someone)” Sometimes people use the term “memorial” to wrongly imply that the Mass isn’t about praying for the deceased but honoring the deceased.
So, if you do use the term “memorial Mass” just remember that it doesn’t mean that the Mass is about honoring the deceased, but praying for the deceased.
