Legal Considerations for Employee Termination
Legally, no, the company does not have a valid reason to terminate the employee. I have been closely studying all precedents. The legal principle that can be used by employers is "No Work No Pay." However, the honorable Supreme Court explained this in the case of Union Of India Etc. Etc vs K.V. Jankiraman as follows:
“The normal rule of 'no work no pay' is not applicable to cases where the employee, although willing to work, is kept away from work by the authorities for no fault of his. This is not a case where the employee remains away from work for his own reasons, although the work is offered to him.”

Advisory from the Ministry of Labour and Employment
The Ministry of Labour and Employment, Government of India, vide advisory no. M-11011/08/2020-Media dated 20/03/2020, having the title “In this critical time of the coronavirus (COVID-19) epidemic, the Ministry of Labour and Employment advises all public and private employers to support their employees and workers,” states:
“In the backdrop of such challenging situations, all the Employers of Public/Private Establishments are advised to extend their coordination by not terminating their employees, particularly casual or contractual workers from a job or reduce their wages. If any worker takes leave, he should be deemed to be on duty without any consequential deduction in wages for this period. Further, if the place of employment is to be made non-operational due to COVID-19, the employees of such unit will be deemed to be on duty.”
Maternity Benefits and Legal Protection
Now, your question is specifically related to maternity benefits. Section 12 of the Maternity Benefit Act provides: "When a woman absents herself from work in accordance with the provisions of this Act, it shall be unlawful for her employer to discharge or dismiss her during or on account of such absence or to give notice of discharge or dismissal on such a day that the notice will expire during such absence, or to vary to her disadvantage any of the conditions of her service." So you cannot do so. See this
