Hi,
We were able to extend the filename name validation functionality to few more characters (say '-' here) in AEM 6.3 assets successfully. The following js file is responsible for filename validation:
/libs/dam/gui/coral/components/commons/fileupload/clientlibs/fileupload/js/fileupload.js
For extending the restriction functionality to few more characters, we need to overlay the above node (fileupload.js) and make the required changes in it.
Changes to be made in overlay location (/apps/dam/gui/coral/components/commons/fileupload/clientlibs/fileupload/js/fileupload.js):

Sample output:

We hope this helps!
