Probably. I suspect SLIP plugs into the Windows networking stack the
same way that PPP does, i.e. through NDISWAN:
or something like it. That's the part of the OS that translates
incoming PPP - and probably SLIP - frames into fake Ethernet frames
before handing them to the Windows networking stack, and transforms
outgoing Ethernet frames being sent over a PPP - or probably SLIP -
connection into PPP or SLIP frames before handing them to the WAN
I'm not certain why it's not possible to transmit on a PPP/WAN
connection, but I suspect that whatever the reason is also applies to

Probably not, unless there's some way in which a driver can put itself
on the "other side" of NDISWAN. I'm not sure there is any way for a
non-Microsoft driver (such as the WinPcap driver) to do that.
