I'm not quite sure I got your question, so please be "understanding" if I misunderstood you.
All *nix based systems have multiple TTY's, usualy 4 but can be 6 or 7 as well.
This includes Fedora
(Simplified)
Other than how they work (backend-under the hood) to provide the GUI, Wayland and Gnome are no different to each other, same for any other GUI/WM/etc....
At any given time - unless you somehow managed to freeze your system - you ALWAYS can press "CTRL+ALT+ {F1...F7}" to switch to the speficic TTY1 - 7.
If I remember correctly, most *nix based distributions use TTY2 or TTY4 as the default GUI-TTY, while the other TTY's could be used for other things - regular console usage, with the exception of TTY1.
And something to clarify, a GUI is not the OS (any *nix, incl BSD etc, Mac, heck, even Windows), this said, both, Gnome and Wayland have the same compatiblity to the underlying OS, this includes - but is not limited to - how they get started from a TTY, as they both rely on the same services and methods.
Hope this helps
If it does not, please wait for someone else to respond or rephrase your question.
Thank you and have fun!
