Quick question, is it acceptable to use tantalum capacitors with this device?

Thank you.

Generally, no. As explained in the D/S, the capacitor ESR is a critical parameter to the operation and output impedance of a charge pump. Tantalum capacitors typically have very high ESR.

Why are ceramics not acceptable?
