Even though DMX cables are based on XLR cables and they will both plug into the same receptacles, there are real differences, the impedance of an Mic cable is only 70 Ohms whereas the DMX has over 100 Ohms of impedance.
The higher resistance of the DMX cable requires more flow of electricity to overcome and creates a more stable data signal. The lower resistance of the XLR cable allows it to pull fainter audio signals to be amplified. So DMX cables can plug into a microphone cable snake and they will work, but with a loss of data quality that may result in stuttering or shaking in the units being controlled.
You can use XLR cables in a pinch, but they are not a long-term replacement for DMX cables.
