All RFM69*** can talk to each other, they are all using the same SX1231h RF chip. This includes: RFM69W, RFM69HW, RFM69CW, RFM69HCW.
However the HW/HCW variants have different power output (20dBm) than the W/CW variants, and need to be configured a little different in your Arduino sketch, see the RFM69 lib examples for that.
