I do not think this is easily possible, as I assume you are referring to a 
renaming of the external file which is done outside emacs. 

Nevertheless, there are ways of achieving this, which depend on the OS you are 
using. For Linux (and OSX) you could create a hardlink to your file. This 
hardlink always links to the file, irrespective if you rename your original 
file. You could then use the hardlink in your org file. 

Other option: use a custom function to identify the file based on the ID by 
using e.g. grep on a the directory where you expect the file to be. 

But I don' think this can easily be done. 

Hope this helps,
