Practically yes, MOT is only required to use a vehicle on a public highway, parking is not really using. The Police will be okay as long as it is taxed. Your insurace company will probably use it to wriggle out of paying a claim.
I would only do this as a last resort now, in my younger days of course I bought a blank mot for £30 in a pub and filled it in myself.
I presume it was last MOT'ed under the new computerised system, then it is on the database and you can still be prosecuted as the Police will be able to check this without needing to see an MOT certificate.
