Read the policy. But If it is so wrong as to amount to a knowingly and / or materially false statement on the application, then I suspect the answer is yes, but a more plausible scenario is that the insurer would go back and retroactively adjust the premium to what it should have been, had the application been completed correctly.
Your state law may also have rules on this.
I have had to provide odometer readings for cars I rarely drive that have a somewhat reduced premium; I usually just send them a picture of the odometer.
