Yes, both should be able to use the Sonos skill in Amazon Alexa’s ecosystem to control music on your Sonos speakers. One important note, you won’t be able to sync them to play the same thing at the same time.

With a Spot and a One online at the same time, when using the Wake command, the Spot executes the command over the One. @Airgetlam is correct though - One and Spot will not play music through both devices at the same time. I have them bundled together via the Sonos Skill settings in the Alexa app (Skill Settings> Manage Smart Home Devices>Groups>Add Group). Doesn't seem to work though.
