Yes, except for the extra transistors which will allow
much more current for brighter LEDs. If you hook the LEDs
directly to the 4017 with a resistor, you only get 2 or 3
milliamps. The extra transistor will get you 20 mA or more.

That's helpful, since I do not yet know the operating characteristics of the
LEDs that I will want to use.
Thanks,
