I don't think so.  Not a georeferenced image or at the original resolution.
You may want to check and add a feature request for it if there isn't one already. 
But I wouldn't be surprised if it was possible to do it from the Python console.

You can also do File>Save as Image in the main QGIS window.
If you "zoom to layer" it should be relatively easy to write a script to pan with the arrow keys (probably easiest with Autohotkey if you are using Windows), "save as image" repeatedly and then stitch the images together (which may be easiest with "Fiji"

Or maybe it would be possible to use qgis-mapserver and a trick like the last post at http://ask.metafilter.com/148540/When-I-said-birds-eye-view-thats-not-quite-what-I-meant
