"Urk" is acceptable, though somewhat discouraged, as an intransitive verb meaning "to go[1] 'urk'". If one really must use it as a transitive verb as you described, it can only be done after filing a formal request for an exception three days in advance (seven days if the request is filed by post instead of electronically), and must be edited and rephrased if the request is denied.
