YES......
Linoleum in our 5vr was laid down for 'kitchen' area and 'bathroom' area.
It extended past actual areas in both. Then cabinets/drawers etc. were set in place and carpet laid.
Carpet padding was held down with 1000s of stables everywhere. I know cause I pulled each and every one when we replaced living area carpet.
We also replaced linoleum in kitchen area and extended it past kitchen area.
The extra linoleum around sink/counter area in living area that was covered by carpet provided a water barrier to sub-floor.
MFG.s might use a little more linoleum in areas as it is faster install then measure/cut to area......but they don't cover the full length in linoleum and then carpet over it. Just not cost effective.
Now if rv came with full linoleum flooring and then carpet ADDED....
The linoleum under carpet would not be presentable after carpet/padding removed due to installers and their happy stable attack....kinda like 'whack a mole'
Wham, wham, wham
