Josh, you might be able to run it -- maybe, but even if it worked, I would think it would be so slow that it wouldn't be worth running (that is, if the programmers aren't lying about the 2 GB requirement.)
Most software companies understand that there are page files to help increase the size of the virtual memory. RAM requirements are usually referring to actual RAM.
About removing linux -- well, there isn't a technical "uninstaller" for an operating system, but that doesn't mean you cannot uninstall an operating system. It can be as simple as deleting the partition that the operating system is on. Don't rush, though. You do have to make sure that the bootloader is configured to boot Windows properly before you do that. Deleting a partition occupied by an operating system doesn't delete its bootloader (as far as I know), and as long as it gives you an option as to what operating system you want to boot at startup, I wouldn't think it would be a problem, but if you are going from a Windows-Linux system to a Windows only system, I would recomend restoring the native Windows bootloader, and then deleting the Linux partition.
If you install Linux, just make sure to install Linux after Windows. The reason for this is that the Windows bootloader doesn't like Linux, and doesn't support it. Whenever you install a new operating system, normally, it replaces the old bootloader. Most Linux distrobutions come with bootloaders that can boot Windows.
I would recommend installing Ubuntu (Ubuntu.com), which is free and is one of the easiest Linux distributions to use. It automatically configures the bootloader when installing. Just make sure that you set it to install to a different partition. If you need help at that stage, ask someone or look it up. I wouldn't think that you would want to mess up there! You might have to go to the advanced options and shrink the C:\ partition by five or six gigabytes, then create a new one manually, and set it to install to that.
One other note. For efficiency reasons, Unix operating systems, including Linux, create a separate partition for the page file. You don't have to create one, but it you aren't short on space, I would recommend coughing up a gig or so for the swap. Remember, no swap partition = no page file. That means that you have only 1 GB of virtual memory to use (assuming you have 1 GB of system RAM). The latest version of Ubuntu likes to use about 400 TO 500 MB of virtual memory when nothing else is running.
