Extending the JTAG cable may work for programming if you're in a fairly clean environment and extend it with good quality cable.

If you are using a longer running program such as the Nios II debugger, SystemConsole, nios2-terminal etc then it will be more affected by errors as it's running for longer (hours or minutes as opposed to tens of seconds).
