The Pico datasheet explains how to do this safely. Section 4.5 "Powering Pico" or section 4.6 "Using a battery charger". You don't need the DC-DC converter but you need at least a diode between the diode and VSYS so you don't accidentally turn the Pico into a battery charger, which could cause the battery to overheat or even catch fire.
I suggest using a battery with a built in protection circuit from a reputable source. Those protect against many kinds of battery mishap.
