No.
It's the amperage that kills. Yes, in reality, 240V circuits are likely to have higher-amperage devices attached. One milliamp at 240V will not kill you.
That's why our defibrillators (I am/was a critical care paramedic) have a set voltage, and if we need to deliver a bigger shock, we turn up the joules for delivery.

If a circuit is formed from a 240 V source, through you, to a low-impedance ground, and to the extent that you can be modeled as a resistive load (quite well), the amperage flowing through you (until the breaker opens, if it does) will be twice the current that would flow through you from a 120 V source in the same situation. Current kills, and 240 V sources provide 2x the current into a load as a 120 V source, if you're the load.
