I'm looking at the Casio WK 6600 keyboard and

MIDI connectors are replaced with a USB - B connector. Can anyone answer:
1. These connections are okay to connect my linux desktop computer to the
keyboard using a standard USB A-B cable?
That is the intention. It should look like a midi port on your computer.
2. How long can the MIDI cable be? I suppose if
it's too short I could
always insert an extension cable?
Assuming you really mean USB cable and not MIDI cable, Yes. Maximum
cable length USB-IF Standard is 5m (16.4 feet) though there are some
passive cables made (Newnex for one) good for up to 10m. Beyond that
you need an active USB cable... depending on what they put in there,
this will work fine or it will give problems.
There are USB-to-LAN-cable extenders that use a LAN cable for longer
stretches. Some of them are comparatively cheap, but the fine print
usually shows them up as "full speed", namely 12Mbps, making them
unsuitable for most soundcards but not for MIDI. But when hubs
(built-in?) come into play with other slow devices, the potential for
"hub problems" grows again by leaps and bounds.
