Is it possible to change the accelerometer on CN0532? If so, what is required to do this?

Yes, it is possible to swap ADXL1002 with ADXL1001 without any modifications to the low pass filter components.

For other sensors in the ADXL100x family, the 3dB bandwidths are significantly different to ADXL1002 so passives will need to be modified to match the frequency range of the sensor.
