I've never done it (that I know of). I'd guess not. Will you try it and let us know?

other then probably being an NEC violation, I'm not sure, wouldn't think there is any reference to ground with them, unlike a florescent ballast which does references ground for the purpose of the lamps, there for a while some fixtures that didn't require Polarization would have just two black wires, like T-3 quartz fixtures, but now I see these fixtures with one white and one black?

Seems like a good share of the solidstate ballasts are multivolt rated so I doubt it really matters. I agree with Larry, try it and report back.

depends upon where the voltage is changed from AC to DC, LEDs are a DC device and if reversed polarity would burn up if reversed, but if the change over is in the track head, I see no problem as AC is non polarized, but if the track system has a grounding rail, then it would be a problem as the head would not be grounded, I have never installed any as of yet so I have no idea on how there built?

There are a few ballasts rated 277v to 480v, which is designed to have either input leg floating 277v above case.
The more common 120 to 277 or 277 to 347v ballasts are not designed to have the white lead more than a few volts over the ground/case and you may compromise reliability.
If it's a programmed rapid start, it may also cause the lamps to have excessive glow current or premature ignition causing less cycle life from lamps compared to proper installation.

So they don't like 240v?

It will be fine on British 415Y/240 when it is connected neutral to leg.
Reliability maybe compromised if it is connected between poles on split phase 240/120 or between phases on 208Y/120 with both leads being 120v above ground.
