No, the Subversion dump file format is not really configured for this. There is no index, there is no way to search for specific files inside the dump file and (there are several different dump formats). I think the delta is often stored in the dump file.
The best way to get files from a Subversion dump file is to upload the dump to the Subversion repository (even temporary). In this way, Subversion recreates all indexes and loads the contents into a form suitable for online access.
