Comment on the possibility of defining a Boyle Temperature if a=b=0
When a = b = 0, Van der Waals equation
PV = RT
That is at any temperature this becomes zero and so all the temperature is Boyle temperatures.

Comment on the possibility of defining a Boyle temperature if a=0
When, a = 0, Van der Waals equation,
P (V - b) = RTor, PV = RT + Pb
Differentiating with respect to pressure at a constant temperature.
The gas has no Boyle temperature since at any temperature.
