No, the official name is Ogg and the recommended filename extension is 
.ogg for all Ogg bitstream files, regardless of content.

Ogg Movie? This extension was promulgated by a set of windows-oriented 
tools, originally to describe "DivX;-)" (beta mpeg-4) encoded video 
and Vorbis encoded audio in an Ogg container bitstream. Now I think the 
tools are more general.

See for example the *nix-oriented 'ogmtools' package 
<http://www.bunkus.org/videotools/ogmtools/> spun off from that project 
(and some experimental code from our cvs). It describes OGM as "Ogg 
media streams".

Just Ogg. We've never endorsed the .ogm extension or any other 
description of Ogg bitstreams.
