I'd suggest yes it's possible, but not at constant height and generally the odds are against it.
If the aircraft has a significant pitch change with power such that the aircraft tends to pitch nose-down when the throttles are closed. Thus the throttle closure would cause a dive (hopefully a gentle one) during which airspeed would increase. This you'd associate with a low thrustline, which is the case on most modern airliners, combined with a horizontal or tail-down angling of the thrustline, which I'm not qualified to comment on.
Highly unlikely, but you could couple this with Fobotsco's scenario and envisage constant height and increasing airspeed (courtesy of sustained rising air).
