No, a Portal action allows similar actions to a Move action, such as using room actions per the rulebook, but it does not count as a Move action. Therefore, Powers or abilities requiring a Move action cannot be used with a Portal action. For instance, Sekhmet's Warden Advance Power cannot be used in conjunction with a Portal action; you must use a Move action to defeat all Scarabs in the room you Portal to. Conversely, if you Portal to a room with enemies and want to use Wally's Silent and Deadly Power, you can do so, provided you have not taken another Move action that turn.
