I cannot speak for Jagex, and 2_Tron clearly feels differently, but I imagine that the fundamentals of what you are trying to achieve are allowed, and I note there are various existing ways to achieve a similar result:
* In the past, when the game was played in a Java applet in a browser, you could easily do it with browser tabs. (By clicking the tabs on-screen, or keyboard Alt-1, Alt-2, etc. to select numbered tabs.) Having said that, this is no longer a supported way to play, and they also used to forbid playing on multiple accounts simultaneously so it was not relevant at the time.
* In Windows 10 and 11 I think you can get a reasonable version of this using the multiple desktops feature, by putting one instance of the game on each desktop.
* Standard Linux window managers will also provide multiple desktop support with keyboard shortcuts, and maybe even better ways of doing it.
* If you are happy with buttons on the screen (rather than keyboard buttons), you could just change your taskbar settings so it doesn't merge windows of the same program together, then click the taskbar buttons when you want to switch.
* For a high-budget solution, you could even have a whole bank of computers and a KVM switch with buttons to select them. (I don't expect you to do this, but KVM switches are not banned and I am sure some players use them.)
* You could look at whether standard Windows 'accessibility' settings also provide a way to do this (or something similar, perhaps with voice control).
Having said this, if you are writing your own software which programmatically touches the Runescape windows - even just to raise them to the front - then it is possible that their systems will flag it, and if this happens then they are more likely to ban you than to engage in any discussion with you about what you're actually doing and whether it should be allowed.
It is probably safer to use an operating system feature - perhaps multiple desktops - even if it isn't quite perfect.
