you can but it may not perform the way you want it to. you will be putting stress abnormally on the spline of the rod. The spline is like a humans spine. going against the grain so to speak is never good.
i would get a rod designed to handle a conventional reel
Tourist do it all the time on the jetties in the summer
Sorry couldn't resist.
Conventional and spinning rods use way different guides. The first few spinning guides are much bigger because the reel spool sits much farther from the rod. If you try to use it for a conventional the line will now be going up to the first guide then down to the tip, not in a straight line. The Spline could also be an issue but very, very few manufactors bother with it, definitely not on a low end rod, they'll build to the curve of the blank.
