Is the equality between action and reaction based exclusively on the
third law formulated by Newton and considered so obvious that it never
needed any experiment to confirm it, or has some experiment actually
been carried out?
Newton based the low on experiments performed before he wrote the
Principia. Later experiments have not found any deviation from the
law.
The equality of action and reaction can be inferred from the law of conservation of momentum, which is also confirmed by all experiment.
