Nope.  For the vast majority of automatic lenses, mounts must match not 
only by brand but often by mount type within brand.  The only automatic 
  lens that can be "adapted" to OM mount is a Tamron Adaptall or 
Adaptall II with OM adapter.  The Tamron Adaptall series was 
specifically designed for interchangeability by using adapters for 
specific camera mounts.  In the 70's Vivitar and Soligor also made some 
interchangeable mount systems similar to the Adaptall series (T-4 and TX 
if memory serves) but, AFAIK, never included OM versions of these adapters.

On the manual lens end of things there are what are known as T or T-2 
mount lenses.  The T and T-2 mounts are the same thing except for a 
minor engineering enhancement to the T-2 mount.  The "T" is for Tamron 
who originated the concept of interchangeable lenses between brands. 
Just like the Tamron Adaptall, a T-mount lens is specifically designed 
to fit onto a T adapter which is made for a specific camera mount. 
Lenses with manually controlled apertures or lenses with no aperture 
control (such as mirror lenses) are often made in T-mount for interchange.

If you have a T-mount lens you can get separate adapters for both OM and 
4/3 mount as well as almost any other 35mm SLR/DSLR.

One of the reasons some of us now own Canyon DSLR's is lens 
interchangeability.  The Canyon EOS mount has a very short registration 
distance and is amenable to attaching OM mount lenses and many others.
