First off... Welcome to the forum!!!
You are mostly correct a browser is a browser but an OS is an OS... ;D ;D
The browser can and most times will report the OS its running on, if not an "approved" OS it can fail.
What you may want to try it a "User Agent Switcher addon" - Where Firefox will then report its running on another "approved" OS...
If the application is strictly web based I don't see where any issues would occur, although should there be calls back to the OS the add-on still may not work..
Just for fun, another thought would be to query the POS software support to see about adding Linux as a supported OS I personally have never used or needed to use the switcher..
