Yes. Connecting two inputs together to ground and tying two inputs together to anything else are two very different things. Remember that a schematic usually is not a physical layout or pc board routing plan. A ground connection daisy-chaining to a bunch of pins does not mean that those pins should be connected together in that order for all applications.
If you look at the 4026 internal logic diagram on the datasheet, you will see that the clock and inhibit are two inputs into an AND gate, one of them inverted. So in fact you can advance the counter with a positive edge on the clock pin with the inhibit grounded, or you can use a negative edge on the inhibit pin with the clock pin tied to Vdd. Both inputs are Schmidt trigger inputs, and this clearly signals the intent of the designers.
