Yes, they are both on the 10.14.140.0/23 network. 

But should that make any difference? pxelinux has always worked fine
for me with the TFTP server being in a different network.

I have a rather complicated pxelinux setup with hierarchical menus,
booting ThinStation, mfsBSD and a dozen useful utilities, and this has
always worked fine for me, across subnets also.
