Well, not really, as MSR stoves are designed to burn a big variety of petro and biofuels, *except* alcohol, as the air/fuel ratio is much different, more like 8:1 versus 14.7:1 for gasoline/petrol. A plastic liner that might make the aluminum alcohol-safe, might be easily attacked by the other fuels.
Trangia stoves burn alcohol, so no surprise their bottles are designed for it.
IIRC, cars that allowed a high-ethanol mixture of gasohol (E-85), required stainless-steel fuel lines (and possibly fuel tank) instead of aluminum or plastic. Such cars have a little corn-leaf symbol and say FFV (Flex-Fuel Vehicle) on the car.
