The term Wake Turbulence is perfectly appropriate during cautionary advisories to aircraft engaged in taxi and ground movement operations. Other terms like jet blast, propwash, etc., may be more specific but the 7110.65 states that these terms aren't mandatory. Here is a note at the bottom of the general control section on the issue:
2-1-20. WAKE TURBULENCE CAUTIONARY ADVISORIES
Wake turbulence may be encountered by aircraft in flight as well as when operating on the airport movement area. Because wake turbulence is unpredictable, the controller is not responsible for anticipating its existence or effect. Although not mandatory during ground operations, controllers may use the words jet blast, propwash, or rotorwash, in lieu of wake turbulence, when issuing a caution advisory.
