No, they have to be stopped in order to reverse things. IMHO that is good practice anyways. For example when doing metric threads, I'll have the lead screw and spindle in normal rotation, and just use the switch at the end of the thread to back the cutter to the start, not opening the half nuts.
Another example would be setting up the reverse tumbler *before* taking a cut with the power cross feed.
Or, reversing the spindle to take a cut on the backside of the part.
I've had to use all of those methods in the last week. In all cases it takes planning ahead, you never shift a manual machine on the fly unless it was designed for it. And the hobby-sized machines that the OP is looking for, won't have that feature.
EDIT forgot to add, yuo can flip the motor switch from forward to reverse without stopping, the SB was designed that way. Any other reversing (ie gears) it obviously has to be stopped.
I am familiar with best practice, but I'm also a stickler for words and answered the op's question
I have a follow up question someone on here may know. Which bench lathes have a forward and reverse linear feed capability without shutting the machine off? I often shave down from decent sized diameters and it would be handy if I could flip a lever to reverse the carriage direction back and forth.

Looks like you found a nice lathe! Not too big and in excellent condition, you might want to pick up a lottery ticket. Some of us old curmudgeons may be getting grumpy, that is what happens when you spend your evenings designing spare parts to keep your body going forever
