You can do this:

#+MACRO: include (eval (org-export-string-as (concat "#+include: " $1 "\n") 
'org t))

and then 

{{{include("myfile.org" :lines "1-10")}}}

will drop those lines into the file as the output of an export to `org'. You 
will need to customize export backends to include `org'. Or you can use some 
other backend if you put the macro call inside an export block.

However, the results may be surprising - macros defined in the main document 
will not function in the included document unless you also defined them there, 
babel code will run out of sync with babel in the main document, and so on.  I 
am not sure how this might affect internal hyperlinks, so try some cases if you 
need that to work before you commit to doing something like this.

So unless what you are doing inside the included document is pretty tame, it 
may not offer you all that you want.

HTH,
