Yes.
You can map up to a 2 GB view (actually several!) into a file of any size on Win32. The upper half of the address space is reserved for the kernel and cannot be used for mapping, even with the /3GB flag (apparently).
I suspect Linux 32-bit has similar behaviour, but don't quote me on that.
There's a diagram on this page: Memory-Mapped Files - .NET | Microsoft Learn
To quote the KB article:
"Multiple views may also be necessary if the file is greater than the size of the application’s logical memory space available for memory mapping (2 GB on a 32-bit computer)."
