OK. I was thinking Play Store - My Apps - All. Non stock apps can be removed with the X there.
You may mean this, or the Applications Manager - All list.
Samsung Link is compatible with my Note 3 but I had it disabled / turned off. I d/l the latest version and disabled / turned that off.
So it shows in my Applications Manager - Disabled (Turned Off) list.
It still shows in the Play Store - My Apps - All list and cannot be removed.
As it is not compatible on yours I would think it would not be on the Applications - All list OK.
However what's interesting is in the Play Store, any Motorola apps (I have a Moto G on the same Google account) which are not obviously compatible can be deleted from the Samsung Play Store app. Likewise all (it seems) Samsung stock apps that cannot be removed on my Samsung Play Store can be removed (X) from my Moto G.
Samsung Link should be removable on your Note 4 Play Store list, but only turned off / disabled from Applications Manager.
Go figure. Sorry.
