No I don't think so.
I even heard that on the "Letto" a Swedish re-branded Bebook One, the Adobe Digital edition implemented on the device had its own "Real-time-clock".
So even if you tried to set back the date, the borrowed epub expired at correct date. I haven't tried this on any reader, but it seems reasonable.
