This seems to be quite an old question and since the Lollipop announcement, I guess it's easy to say that yes, since the Leanback API has been integrated in a support library.
compile 'com.android.support:leanback-v17:21.0.0'
I actually had some fun implementing the samples and my custom apps using it on Android KitKat and it all works like a charm.
Interesting to say though, you won't have the nice transitions as you can see them on Lollipop.
Edit: It is important to know that the leanback library supports all API levels starting from 17. However, you won't have all transitions and the BackgroundManager will not work prior to API 21.
