I recall the low-voltage warning is set at about 4.6V for the 5V rail, though the exact point varies by product and revision and of course the manufacturing tolerances of the monitoring chip.
The SoC, SD Card and other 3V3 supplied components should work as expected so long as they are powered by 3V3, so long as the voltage into the regulator or PMIC is high enough for it to supply that 3V3.
I don't see how the SoC, SD Card or any 3V3 component supplied with 3V3 could or would be damaged, would fail or behave unexpectedly, under those circumstances.
