For all practical intents and purposes, yes... the Orbi system is "mobile" in the sense that you can unplug it from your modem at home, plug it into the modem at your vacation home, and expect it to work without any reconfiguration.
(I would recommend, though it is not strictly necessary, that you run the QoS speedtest tool in the router's configuration panel once the system is started up after moving it between houses just to ensure that the router's Quality of Service algorithm is calibrated for the speed of your connection at that location to give the best performance.)
