Generally not. Maybe it can happen in some unfortunate cases, but it is not at all likely.

Electrical arcing is much less probable with a digital lok than with an analog one. The motor contains coils, which can create high voltages if the circuit is broken abruptly. In an analog lok, those high voltages can go directly out on the track and cause arcing. The digital decoders contain protection circuitry, mainly to protect the decoder electronics. But this also stops the high voltages from reaching the wheels and pick-up shoe. There is some protection in the analog loks too, but not at all to the same degree.

Also the distance between the wheels on the axle is important. Pls. see further in this topic:
