Sure

Any partition other than the Windows partition can be removed and Windows will be fine with that. Some old versions of Fdisk would not delete non-windows partitions, but any Linux partition tool and many 3rd party tools will let you delete a Linux partition or a swap partition if your Microsoft partiton tool wil not. Of course, if you want the space back you'll have to create a partition type that your Windows can use. I would strongly advise just adding a partition back rather than resizing a partition. It will likely end up being a logical drive in an extended partition, but the exact nature depends on your existing partition structure, which you didn't list.

You don't gain anything by removing the Linux partition unless you do something to recover the space, if you don't plan on doing that, just leave it alone.

As for Lilo, if you installed it in the Linux partition, then it's gone when you remove the partition. If you installed it in the MBR (which is much more likely for anyone who would ask this question), then you need to leave lilo alone or replace it with something else that can boot your system. Lilo is apparently doing this job for you, so it's not clear why you want to remove it. Exactly how to replace it again depends on which version of Windows you are using, which you didn't say. Old versions of Windows that used fdisk had a secret option in fdisk that would rewrite the MBR. This is the /MBR switch, the command fdisk /mbr should replace the lilo boot loader with the plain MS boot loader on such systems. I expect there is an easy way to do it on XP as well, but I don't know it off-hand. Or you could just write something else to the MBR. Smart Boot Manager installs to the MBR cleanly and gives a handy (but crude) boot menu, you could install it. That would overwrite lilo if you feel there is some need to do so. Personally I like XOSL, which needs a little extra disk space (I like to give it it's own small partition but the documentation claims it can live on the Windows partition), it also installs it's own code in the MBR and gives you a very nice and handy good looking boot loader screen.
