The Raspberry Pi Zero W is pretty similar to the Raspberry Pi B+. You
can use the standard Rasbian or any other Linux distro meant for the
Raspberry (there are several.)
The 40-pin extension header is also the same as on the other
Raspberries, so you can use all the manuals and premanufactured
extensions boards OOTB. The only things that are missing are the bulky
USB-A and Ethernet connectors. (It even has HDMI.)
Bitbanging onewire is supported through the w1 kernel driver. That's the
same as with the Arduino Yun, I think.

Both the Arduino Yun and the Raspberry Pi Zero W have similar power
requirements. About 2W for the SoC.
If "by battery" you mean a "small battery" then - forget it. Wifi alone
need about 600mW of power. That's for any board.
