No. Fatal signals, such as SIGTERM, are caught by a signal handler,
which runs emacs.c:shut_down_emacs. `kill-emacs' in a nutshell runs
`kill-emacs-hook' and then also calls shut_down_emacs.

I don't think it's a good idea to run Lisp code from within a fatal
signal handler. shut_down_emacs saves all unsaved buffers and cleans
up the terminal, but doesn't do anything else, because Emacs's
internal data structures can be very unstable at this point.

Sorry, I don't know. Someone else will have to answer this.
