Sure, but unlikely. Have you considered that conspiracy theories like that may have been concucted by the Iranians to distract attention away from their culpability?
They were on high alert, their crews have authority to launch at their own discretion, their nation had just fired missiles at a hostile power known for overwhelming use of cruise missiles and air power, they saw a target at low altitude, assumed the worst, did not double check target parameters were indicative of a civilian, and fired. Tragic mistake. How's that for a theory? Especially after the Iranians admitted it.
