Being a sole proprietor I use my personal credit card for business expenses. Can I write off business expense paid with spouse's personal credit card on joint tax return?

Yes, you can write off business expenses paid with business card, your personal card and spouses personal card.

Just keep good detail of what was paid for as when you get personal expenses and business expense together it gets more difficult to track the business ones.
