Is it acceptable to say 'Can I borrow this classroom / hall / piece of land / your home phone, etc.?" Thank you most sincerely.
Why can't a phone be moved?

I assume the OP meant that it can't be taken from the house, in the way that if you asked a friend if you could borrow a book, you would probably mean that you wanted to take it home.
Their home phone is probably attached by a cable to the wall. The use of "to borrow" in that scenario isn't entirely correct but I daresay we all use it. We should say "Can I use your phone?"
By the same token, "Can I borrow your toilet?" is frequently used (in the UK, at least) - that would be bathroom/restroom in the US. Of course it's ridiculous to suggest that you're actually going to borrow an item of bathroom furniture but we still say it.
I think "borrow" meaning "to make use of" is pretty common for a lot of uses.
But "Can I use..." is also pretty common for these too.
(Giving my west side of the Atlantic opinion.)

You may borrow my classroom, my conference hall, a parcel of my land for your summer garden, my phone, my pen or pencil but you may use my toilet only if you aim properly and raise and lower the seat.![]()
Lower the lid?
Oh my - that guarantees dinner out with a bottle of bubbly.
