Yes. But here's what I learned that may help.
A good scale helps with hops, because depending on the style the measurements might get a little small. If that's a problem for bittering additions; substitute a lower alpha acid hop for any 60+ minute additions of Nugget, Magnum or similar high alpha hops. Otherwise 1 or 2 pellets may be too significant of a difference.
Another caution is with boiling. It's easy to get a more vigorous boil and thus greater evaporation with 1 gallon than 5. Adding to that, many stove top saucepans diameter to height ratio is worse than a brew pot. So monitor your volume throughout, possibly metering back the heat or diluting as needed to hit the target OG.
I usually transfer all the wort to the fermenter rather than lose a decent amount to trub. It's really easy to crash cool in the end by putting the jug in a fridge and get a dense cake when finished fermenting. Then I normally bottle straight from the jug with a mini auto siphon held just off the cake.
