yes.
Or… fill your personal .Xmodmap with:
keycode 115 = Multi_key

And add on your .xsession file:
xmodmap $HOME/.Xmodmap

Restart your session and use your compose key and letters…

Or, if you use Gnome/KDE/Xfce, go to the Settings > Keyboard > and modify the Touch Compose. ;)

If I'm not wrong, by compose touchs, as:
<kbd>CTRL+Shift+U+0+0+F+1</kbd>

See the unicode for the ñ:

And see the Compose manpage:
