Does a charge radiate EM waves in non-inertial frame?

Question

A charge at rest would not emit EM waves but an accelerated charge would. But what if the observer is itself accelerated, will charge radiate EM waves as laws of physics should be same for all observers, right?

Answer 1

But what is the observer is itself accelerated, will charge radiate EM waves as laws of physics should be same for all observers, right?

Wrong. The laws of physics are the same in all inertial frames. In other words for all inertial observers. By your assumption, the observer is accelerating. If the observer is accelerating under gravity, then according to General Relativity, they are an inertial observer. But any observer that is accelerating because of a thrust, (such as a rocket under thrust, a car accelerating because of its motor etc.) is NOT an inertial observer.

If a charge is not emitting an EM wave in any inertial frame, then it will not be emitting an EM wave according to an observer who happens to be non-inertial.
