None of the emojis are independently removable. All device manufacturers, including Android, simply support the latest standards approved by the Unicode Consortium so they are the same across every device. If you want to suggest changes to the emoji set, you would need to contact the Unicode Consortium for it to be removed, and that would then be reflected across every device manufacturer.

More information about the Unicode Consortium and how the emojis are evaluated can be found here.

Again, no device manufacturer, whether it is Apple, Google, or Samsung creates their own unique emojis, all of them are included in the latest data set approved by the Unicode Consortium and the manufacturer just adopts that complete data set.
