I believe it is possible, looking at information from both the unicorn and the demon realm silver.

In terms of the silver, while it is typically human women that get transformed if the silver is imbued with demonic energy as suggested with this text '''*By infusing weapons made of demon realm silver with demonic energy, it's even possible to change human women into monsters. This is because when a human woman is cut, the demonic energy dwelling within the weapon will flow into her, as if to fill in the hole where her energy leaked out.*'''

As for unicorns, reading this text '''*A unicorn's own demonic energy protects it against demonic energy from the outside, so it normally causes no problems. However, if her husband cheats on her and demonic energy from other monsters accumulates in his body; or if she has sex with a man who has had sex with monsters many times instead of a virgin, then she'll be helpless to prevent it and demonic energy will be poured inside of her.*'''

Now while the quotes may not directly conclude a unicorn could change into a bicorn when cut. There's also the case of how demon realm silver works. When cut by regular demon realm silver (that has not been infused with demonic energy) the demonic or spirit energy of the victim leaks out. As the demonic energy of the unicorn usually protects it from outside demonic energy, if the unicorn us cut, their won't be enough of their own demonic energy to protect itself from invading demonic energy from another monster. If the blade was infused with demonic energy from a mindflayer, alaraune or any other monster, then the invading demonic energy would mix with the unicorns and transform her into a bicorn. If the blade was infused with her own demonic energy, or maybe even a fellow unicorn's then no change would happen.

But if you had demon realm silver on its own, it likely wouldn't do anything either, depending on the locale. If the cut happened outside a demon realm, then perhaps nothing changes for the unicorn but if the cut happened in a place like Lescatie, then the surrounding demonic energy would like flow into her and change her into a bicorn too.
