No, the inductance and capacitance of the cable will get you if you're not
careful. Remember that video (TV type) goes to 4 or 5 MHz, and what's more,
all frequencies in the range 30 Hz -- 5 MHz have to be passed equally well,
with no difference between the highest and the lowest.
  
  However, you can use a wire of any (reasonable) length if it's a 
  coaxial cable of known impedance, and the driver and receiver (at the
  two ends) are matched to that impedance. This is a way of making
  inductance and capacitance cancel each other out. It's what makes
  large TV studios possible.
