It shouldn't as the interview will be at same application support center. The only problem I foresee is if the address change was made so late that interview notice was sent to old address and you don't get the notice and fail to appear at interview. You would be denied the green card for abandoning case by non-appearance.
You can file an AR-11 change of address form on the USCIS website. Also, make sure to change the address for all pending applications such as your I-485. If done properly, it will not affect or delay the approval of your green card application. You may also want to call USCIS to make sure they have the correct address on file after you do the change of address online.

No. That does NOT delay the processing or approval of your application in any way. Just make sure to wait until you receive the filing receipts from USCIS before filing the obligatory AR=11 Address change form at www.uscis.gov Save a copy for your records and for extra security, after 2 weeks, not before call the CIS nationwide toll free number to ascertain that CIS now has your correct address.
