List invited, co-authored conference presentation on CV as student
If you are listed as a co-author, I'd say yes, include it. You could list it in a separate section of your cv below other, more personal work. If you are asked about it, you can describe it as you do here. This is even better if the reason for the invitation was the work itself and not only the stature of the professor. 

But it would also be good to get advice from your professor on this.
