No, that's the file name that is randomly generated and then sent to you via the web server to your browser. You would get conflicts if it was the report name as multiple users run the same report at the same time.
That said you can get the report name as the file name if...
- Save the report to a file system. Link to docs (http://pic.dhe.ibm.com/infocenter/caapps/v10r1m0/index.jsp?topic=%2Fcom.ibm.swg.im.cognos.ug_cra.10.1.0.doc%2Fug_cra_id10205System-WideReportOutputLocation.html)
- Apply the following script to rename the saved outputs to the report name.

For item 2, you could technically build your own script to also do the renaming using the file pairs (report and xml).
