Yes. Under :help 'runtimepath' you will see that Vim looks for its
runtime files in several directories. For instance, on Unix-like
systems, the following directories aree checked in the following
order:

~/.vim (under your home directory) for your own scripts
$VIM/vimfiles (a non-version-dependent location) for the sysadmin's
system-wide scripts
$VIMRUNTIME — ONLY for scripts distributed with Vim, any Vim update
may silently replace any of them
$VIM/vimfiles/after — for the sysadmin's "after" snippets, to override
any of the above
~/.vim/after — for your own "after" snippets, to override any of the above.

As you can see, you have the first and last word about any aspect of
Vim's runtime configuration.

In addition, the :packadd command may add additional directories, each
specific to one package. For instance, $VIMRUNTIME/vimrc_example.vim
includes the following at is very end:

" Add optional packages.
"
" The matchit plugin makes the % command work better, but it is not backwards
" compatible.
" The ! means the package won't be loaded right away but when plugins are
" loaded during initialization.
if has('syntax') && has('eval')
packadd! matchit
endif

This adds $VIMRUNTIME/pack/dist/opt/matchit to the 'runtimepath'
option to enable the matchit plugin.

You should NEVER modify anything under $VIMRUNTIME because any Vim
update may silently remove anything you change there. But you may
override those scripts with your own, see above.

Both are possible. Or you could (depending on how each server finds
the shared files) put a symlink or a "source" statement to it at the
appropriate location under ~/.vim (for Unix) or ~/vimfiles (for
Windows) in your home space on each server.

Vim 7.4 is old stuff. Nowadays it ought to be /usr/share/vim/vim81/...
