Of course.
But be careful about who you believe when calculating the additional loss. The
absolute best info about this is at Dan's site: https://ac6la.com/swrloss.html

How much return loss is acceptable certainly does “depend”.
I’ll throw in another consideration to further complicate matters:
The higher the VSWR, or lower the return loss, the more power is lost in the
cable due to the mismatched condition.
How much power is lost depends on the type of cable, the cable length, the
quality of the cable and of course the frequency.
The higher the frequency the more power will be lost in the cable due to the
mismatch.
So while your transmitter and or antenna tuner may well be able to operate into
an increasingly high VSWR (or low return loss) the price you will pay for that
is more power loss in your cable.
Thus, return loss becomes more important as you operate higher in frequency or
use longer cable runs.
Not too important at 160 meters but probably very important at VHF.
