Yes.  In fact, if your company has had its securities traded on what London’s AIM considers a “designated market” for at least 18 months prior to admission to London’s AIM, a “fast track route” can be utilized.  What this means is that you do not have to produce a formal AIM Admission Document but rather issue a brief, but detailed, pre-admission announcement at least 20 days before the expected date of admission to London’s AIM.  Your company would still have to engage a Nominated Adviser and a Nominated Broker in order to initiate the process.
