RefTeX uses (buffer-file-name) at 37 locations for various reasons.
Maybe we could get away with having a reftex-buffer-file-name defined as
(or (buffer-file-name)
(buffer-name))
For the time being, can't you just `C-x C-w /tmp/tmp.tex RET' to make
the buffer file-visiting?

That's generally good, yes. The thing is that RefTeX is a multi-file
mode which tries to parse all files belonging to the same document,
e.g., when your document looks like
main.tex
chapters/c1.tex
chapters/c2.tex
appendix.tex
Of course, you don't need that in your very use-case.
