Looking at pictures of the AIR-LMC352 online, I don't think it will fit.
While it doesn't have the bulbous antenna other 802.11b cards have, it also doesn't have the recess that the Apple card has. You see, Apple's card has a recess in the end where the antenna plug in so that the overall card size *including antenna connector* fits within the PCCard dimensions. If I remember rightly, there's no room inside the machine for the antenna connector outside the card's bounds.
Then, of course, I have to wonder why you're looking at this card, anyway. It's more expensive than the Apple AirPort card and the only difference appears to be the second antenna connector, which you can't use, anyway.
