What about the opposite. If the equipment
would tolerate the 50 Hz frequency would US 240 V equipment run on EU 230 V supply?
split phase systems are not "out of phase", if one takes the waveform from the perspective of the two hot wires, then all you have is 240VAC single
If one takes it from ground or neutral, one sees a "out of phase " system, its however a measurement delusion.
A EU cooker ( range) on US splitphase, will see exactly the same potential waveform as that cooker on a floating neutral EU supply.
Yes there are specific safety
issues, for example the assumption on an EU boat that "neutral" is at ground or near ground can cause issues.
Frequency and certain safety installation
issues aside, there is no issue.
Again the reverse is true, leaving aside some safety issues with very old US 240 equipment
so as long as the frequency is an issue ( generally with some motors) its all the same type of electrons !!!
