Can Mac OS 10.5 disc repair a 10.4 installation (PowerPC))

Hi I have a quick question here i have an old iBook with Mac OS 10.4.11 installed and when i run the "Verify Disk" option in Disk Utility i get some bad messages and it recommends me to repair the disk. The problem is that to do that i need a powerpc Mac OS 10.4 installation disk to boot from but i lost it years ago but i do have a 10.5 installation disk laying around and i was wondering if it is safe to do the "Repair Disk" option from that on my 10.4 installation.

Thanks in advance!

Thanks! ill give it a try
