Or course you can, but it is not recommended. There's no maximum distance, just account for x dB loss per coax length. See for example this calculator:

Don't know if it's accurate but you get the idea. E.g. 9 feet of the popular RG-316 at 5.8Ghz has 6dB loss. Hence you'll throw away 75% of your incoming rf-signal, so in this example you'll half your flying range. There's no simple yes/no answer, you must decide whether this is acceptable.
