The system requirements and design of 10BASE-T are fairly different from those of RS-232 and I don't think you can draw conclusions about what one can support in distance based on the other. For instance, RS-232 uses single-ended drivers and can be run over ribbon cable; 10BASE-T uses differential drivers and (because of its high frequency) should only be run over twisted-pair cable.
