Probably, depending on the hub various bits will pull off (although they'll be seized because they'd have been installed dry ages ago) unless there's either a 5mm Allen in the centre of the axle or some spanner flats in which case undo stuff. That hub looks like the axle runs right through and the cap and the silver and black but should remain (but may not) together and pull off, a round axle vice helps. Then twat the axle through with a hammer once off. You might have more luck supporting the hub shell and twatting the axle to start with if it's made up like I said it might be and then separating everything.
Cap as in the black bit of plastic that has 29-08 on it?
