Yes, see variable `org-emphasis-regexp-components': it is a list
describing how an emphasis span (bold, emphasised, strike-through
etc) is "built".

It's fifth component is the number of newlines allowed whithin such
a span. It's set, by default, to 1.

You can modify it like so

  (setf (nth 4 org-emphasis-regexp-components) 4)

to allow 4 newlines in your emphasis span. You have to reload
Org for it to take effect, so the best might be to have this
somewhere in your Emacs init just before loading Org?

Perhaps someone with a more elegant approach can chime in.
