Can I use TP4056 1A to charge lithium battery of 3.7V 150mA?

You want to read the photo of the linked product thoroughly. It tells "change resistor for different current". That's in fact necessary to charge a small cell with this module.

Okay. But if I didnt add resistor and use as it is with the 3.7V 150mA battery. Will it harm?

A Lithium battery is rated for a CAPACITY, not a current. It is 160mAh which means it can supply 160mA for 1 hour.
If you overload it maybe it could produce a current of 1.6A for a few seconds and explode.

Its recommended charging current is probably 0.5 to 1 times its mAh capacity. if you charge it with 1A then it will probably explode and catch on fire.

as per datasheet use 10k Res. for 130mA charging current .
