Can I change New Customer Profile, Change Company name to Wedding date?

I've got you covered in editing customer profiles in QuickBooks Online (QBO), @info2029. 

You can edit the customer profile to alter its company name to a wedding date. However, changing it will also do the same to your customer display name.

To start altering their company name, you can follow the steps below:

1. Go to the Sales menu and navigate to the Customers tab.
2. Locate the particular customer you want to make the changes to.
3. Tap it and click the Edit button.
4. In the Company name section, type in the wedding date you want to enter.
5. Apply the other changes you want to make, and click Save.

Stay on top of your sales transactions by regularly checking the status to ensure everything is on track. You can check this article for the complete guidelines: View sales transactions in QuickBooks Online.
