Yes a wolf can kill a mountain lion especially if the mountain lion is alone and the wolf comes in a pack which is what most wolves do.
Most wolves hunt in packs and so if there's more than one wolf and just one mountain lion then the wolves could easily overpower the mountain lion and kill it.
Even when a wolf is alone they can sometimes kill a mountain lion as well but it depends on the strength of the mountain lion.
Also mountain lions do scream like a woman when they are in danger or in heat.
It's more common to hear a female mountain lion scream like a woman when the female mountain lion is in heat and ready to mate.
The sound that the mountain lion makes is like an injured or dying woman or a woman that is scared and being attacked.
Male mountain lions make a scream like a woman as well but mostly the female makes a scream like a human woman when they are in heat.
The female mountain lion typically screams like a human woman because when it's in heat the female mountain lion is alerting a male mountain lion that it's in heat.
The female mountain lion is screaming so that hopefully a male mountain lion will hear their scream and come to them so they can mate and make baby mountain lions.
