Um, the cog spacing and cogs are both narrower, so 10s speed chain is
narrower (and possibly more flexible?) than 9s. Using 9s chain will make
you more vulnerable to skating and other shifting woes, and is probably
not a good idea, and I say that as someone who runs a tricksy Shimagnolo
drivetrain.
Is this a case of just having a spare 9 chain around, or do you have a
better reason for trying this trick?
Also, rbt generally offers more sensible arguments on these sorts of
matters. To the extent that "sensible" applies to anything in the r.b.*
hierarchy.

I've used a 9 speed Wipperman connex chain (with a SRAM 9 speed link) for
training and a 10 speed one for racing for ages without any problems. I
use the SRAM 9 speed link because its slightly narrower than the connex
one (and also less likely to unlink itself). Recently I've also started to
use the SRAM 10 speed chain for racing.

9 speed chains are cheaper than 10 speed ones.
