Wine will run any EXE as long as you start it (or your desktop
environment starts it) with `wine foobar.exe`. If you start it with
`./foobar.exe` instead, the file must be executable and binfmt must be
set up correctly.

Interestingly, it looks like Arch Linux and Ubuntu have both started
to mount FAT32 filesystems with the "showexec" option. This makes EXE
files on USB drives executable automatically. (It doesn't look very
smart, it just turns on executability if the filename ends in ".exe".)

So I stand corrected; you're right that it's no longer necessary to
change the mount options or copy the EXE to another filesystem. Still,
no desktop environment is going to execute files off of a USB drive
without asking.
