Can AS923 and AU915 networks coexist in the same area?

Yes, as long as they are operating on different networks such that AS923 sensors talk to the AS923 gateway and vice versa for AU915 devices. 

Can the RS1xx AS923 (455-00063) work with an AU915 gateway which uses overlapping channels to AS923?

No, an RS1xx AS923 sensor will not work with an AU915 gateway because it cannot receive the downlink packets due to differing bandwidth and frequency plans used and therefore will drop off the network.
