As mentioned in some of the other replies, waterjet can do this.
Waterjets are used for cutting glass quite frequently for the stained
glass, archetectural, artistic, and optics markets. Note: if what you
mean by "toughned glass" is "tempered glass", then the answer is "No,
you can't cut it". If the glass is truely "tempered" then there is no
known way to cut it - even waterjet, unless you anneal the glass
first, then cut it, then re-temper it. A waterjet can cut
bullet-proof and just about all other kinds of glass, though.
Even with waterjet, and even if the glass is not tempered, there is
still some risk of cracking durring the piercing process (like if you
need to cut a hole). If you plan to have this waterjet cut, be sure
to find a shop that has experience with working with glass, and
equipment that has low pressure piercing capability. (or just cut from
the side of the glass without piercing)

There, you can learn the capabilities of water jets (abrasivejets,
actually), and there are links to hundreds of job shops around the
world that can do the work for you if needed.
