If what you want is that :
wireless clients associate to and SSID for vlan1.
And the AP belong to another vlan (Vlan4 as an example)
-Yes this is possible.
but
-switchport must be set as trunk allowing only these 2 vlans.
-Vlans must be configured on the AP.(under services on the gui interface)
-SSID must be attached to a VLAN. (under SSID manager)
