This is very dependent on which exact VT terminal you're talking about.
For the VT300 series, there is no way to incorporate the status line
as part of the main screen, although some implementations (eg, DECterm,
a VT320-level implementation on DEC workstations) allow you to select
the status line or not, and also allow you to set the size of the main
screen (up to perhaps 72x132 or so being reasonable if you have a
1280x1024 screen), which gives you much the same capability that's being
asked for here. However if the host software requests a status line, the
DECterm will helpfully create it for you (keeping your main window the
same size but possibly making the entire window too big to quite fit on
the screen if you've made it big).
The VT420, on the other hand, actually does allow you to combine the
status line with the main screen so that you get true 25x80 screen
addressing but no status line. It also allows you to set the terminal
in 36 or 48-line modes, but I think those include a separate status
line. I don't know offhand what the VT420 does with the "Select Status
Line" commands if it's in 25x80 mode; the terminal I've usually
experimented with for such questions is on the other side of town, and
the documentation around here is vague on the subject.
The subject of compatibility with VT-series status lines is rather
subtle. I have yet to see any terminal emulator, commercial or
otherwise (including Kermit and even DEC's Pathworks terminal
emulator, I might add) that quite gets it all right.
